Start by rinsing and thinly slicing the medium English cucumber. Next, halve the cherry tomatoes and finely slice the small red onion. Dice the ripe avocados into bite-sized pieces, ensuring they’re creamy for the best texture. In a large bowl, combine all these vibrant ingredients.

In a small jar, add 1/4 cup of olive oil, 3 tablespoons of freshly squeezed lemon juice, and 1/4 cup of chopped cilantro. Sprinkle in 1 teaspoon each of salt and black pepper. Secure the lid tightly and shake vigorously for about 30 seconds until all components are well-blended.

Carefully pour the dressing over the assembled salad ingredients. Using a large spoon, gently toss everything together for about 1 minute, ensuring that every piece of cucumber, tomato, onion, and avocado is coated with the flavorful dressing.

To maintain the freshness and bright appearance of your avocado salad, serve it immediately on chilled plates. If storing any leftovers, place them in an airtight container to preserve the ingredients.
