Give the cucumber, cilantro and tomatoes a good rinse.
Finely chop 1/2 English cucumber, 2 Roma tomatoes, 1/4 red onion, and the flesh of 2-3 avocados. (I used 3 smaller avocados).
Add to a mixing bowl along with 3/4 teaspoon salt and some freshly cracked black pepper. Combine well and take a taste. This will give you an idea of how much dressing you'll need.
Add 2-3 tablespoons Lime Cilantro Dressing (or more) and mix well.
Top with a sprinkling of Cotija cheese and freshly chopped cilantro. Serve immediately.
For the Lime Cilantro Dressing, add 1/4 cup olive oil to a blender or food processor along with the juice of 1 lime, 1/2 jalapeno pepper, 1 garlic clove, 10-15 sprigs cilantro, 1/2 teaspoon salt, and some freshly cracked black pepper. Combine well.
