This simple salad recipe centers on crisp cucumber slices, ripe avocado chunks, and bright tomato wedges tossed together with a whisper of red onion for a gentle bite. The cucumber provides hydration and crunch, while the avocado contributes healthy fats that make the dish feel substantial without heaviness. Tomatoes add sweetness and a pop of color, creating visual appeal as well as flavor balance. A light drizzle of olive oil, a squeeze of lime, and a sprinkle of salt and pepper amplify the fresh produce rather than masking it. It’s ideal for meal-prep, quick lunches, or a side dish that won’t derail a busy day.
Cilantro lime vinaigrette is the key finishing touch, brightening the plate with herbal aroma and citrus lift. Whisk lime juice, a little olive oil, minced cilantro, and a pinch of salt until emulsified. A hint of garlic powder or finely minced garlic can be added if you enjoy stronger flavor notes. The vinaigrette clings to avocado and cucumber, letting every bite be a cohesive, refreshing experience. Serve immediately for best texture, or refrigerate the components separately and combine just before eating to preserve the crispness of the vegetables.
A bright, satisfying lunch that travels well and keeps well.
For a pantry-friendly version, rely on common produce and a few staples that most kitchens already stock. The cucumber and tomato form the salad’s backbone, while the avocado offers creaminess that feels indulgent without being heavy. Red onion brings a sharp, peppery counterpoint that wakes up the dish, especially when sliced thinly. Cilantro adds a distinctive herbal note, and lime juice introduces a clean acidity that makes the flavors pop. This combination makes the salad resilient in flavor across different days if you’re packing lunches, since citrus helps preserve brightness and the fats from avocado slow down wilting.

To optimize texture, dice vegetables uniformly and avoid over-mixing, which can break down avocado. Adding a quick sprinkle of sea salt just before serving enhances flavor in every bite. If you’re not fond of raw onion intensity, rinse the slices briefly in cold water or marinate them in a tiny amount of lime juice for a mellower bite. Include optional add-ins such as sliced olives, crumbled feta, or toasted seeds for different textures and nutrient boosts. The dressing should be balanced: enough acidity to lift flavors but not so much that it overpower the vegetables’ natural sweetness.
Crisp, fresh flavors with creamy avocado and tangy lime.
Packing this salad for work or school is straightforward. Choose a sturdy container with a tight lid to minimize leakage and texture loss. Keep the avocado half separate until you’re ready to eat, or use lime juice on the avocado to prevent browning. The cucumber stays crisp if kept cool, and tomatoes retain juice that can mingle with the vinaigrette over time. If you anticipate a longer interval between prep and lunch, consider adding a few crunchy elements like toasted almonds or sunflower seeds on the day you plan to eat it. Flavor improves as ingredients mingle, so a brief rest can be beneficial.

Reheating is not required, and the dish shines best served cold or at room temperature. A quick toss just before eating re-distributes the dressing and redistributes moisture for a fresh feel. For a more substantial meal, pair the salad with a whole grain like quinoa or farro on the side, or mix in chickpeas for plant-based protein. If you have an herb garden, a few extra cilantro leaves or dill sprigs on top will elevate the aroma and introduce a garden-fresh finish. The vinaigrette already contains lime, but a tiny squeeze at serving can refresh the lime note.
Effortless preparation, adaptable ingredients, and lasting freshness.
A well-balanced lunch should satisfy beyond lunchtime hunger, and this salad does exactly that with a mindful blend of textures. The cucumber’s snap contrasts with avocado’s silken mouthfeel, while tomato’s juice rounds the edges with natural sweetness. Red onion provides dimension without overpowering the dish, especially when sliced thin. A cilantro-lime vinaigrette adds complexity, combining herbaceous brightness with citrus lift that makes the flavors feel clean and modern. The result is a dish that tastes fresh in the moment and remains appealing the next day when stored properly.
If you want to customize, swap cilantro for parsley or mint to explore different aroma profiles. Add a pinch of chili flakes for a gentle heat, which can wake up the palate when you’re more sedentary in the afternoon. A drizzle of balsamic glaze is another optional twist, giving a tiny tangy sweetness that complements tomato. The base recipe remains intact with cucumber, avocado, tomato, and red onion—ensuring a dependable framework for experimentation. Keep in mind that each substitution alters texture and moisture, so adjust dressing components accordingly for balance.

Flavor-rich, easy to assemble, perfect for busy days.
Emphasize knife skills that respect the vegetable shapes you prefer. Slicing cucumbers into half-m moons or rounds, dicing tomatoes, and chunking avocado all require similar but distinct approaches to maintain uniform bite sizes. Red onion can be minced or sliced, depending on how strong you want the flavor to come through. A consistent cut ensures even distribution of dressing and prevents some bites from feeling bare while others feel overloaded. The cilantro’s tender leaves should be added last to preserve their bright aroma, which can fade if subjected to prolonged mixing.
A practical grocery list helps ensure you have what you need for multiple lunches. Pick up firm cucumbers, a ripe avocado, and a couple of solid tomatoes. Red onion adds bite, while cilantro provides the signature herbal finish. Olive oil, lime juice or a bottle of lime vinaigrette, and salt pepper round out the essentials. Optional extras include feta cheese, olives, seeds, and even a protein like grilled chicken or beans for a heartier meal. With these ingredients, you can assemble the salad rapidly and consistently across several days.
The health benefits of this salad come from the trio of vegetables and the healthy fats in avocado. Cucumbers deliver hydration and fiber, tomatoes contribute lycopene and vitamin C, and cilantro offers micronutrients and flavor. Avocado supplies heart-healthy monounsaturated fats that help with satiety, which can support portion control for lunch. The lime vinaigrette provides acidity and a zing that can curb cravings for less healthy options. Together, these elements create a meal that sustains energy without causing heaviness or sleepiness.
As a versatile daily option, this salad adapts to seasons and personal preferences. In warmer months, serve with a light citrus herb dressing and a sprinkle of fresh mint. In cooler seasons, add roasted corn or bell pepper to introduce sweetness and color. For dietary needs, it’s easily dairy-free and vegetarian, with protein add-ons available without complicating the core flavors. By keeping the preparation simple and flavors bright, you’ll reach for this salad again and again for quick, nourishing lunches that don’t require long kitchen time.
