Thinly slice the red onion then pinch it with your fingers to separate the layers.

Step 2

Soak it in cold water for ten minutes to soften its flavor.

Step 3

To a mixing bowl, add diced tomatoes, cucumber, and avocado, the sliced onion, and chopped parsley.

Season with olive oil, lemon juice, salt, and pepper then toss gently until the salad is coated in the condiments and slightly creamy from the avocado. Taste and adjust for salt before serving.
