Begin by gathering a large mixing bowl and chopping your vegetables. Dice the ripe Roma tomatoes, slice the English cucumber, and thinly slice the red onion. Carefully dice the avocado, ensuring it's creamy but not overly ripe. Lastly, chop a generous amount of fresh cilantro. Combine all the ingredients in the bowl, creating a colorful medley.

Drizzle the fresh lemon juice and extra virgin olive oil over the chopped salad mixture. Using a gentle folding motion, toss the ingredients together, ensuring every piece is coated in the zesty dressing.

Just before serving, sprinkle a pinch of sea salt and freshly cracked black pepper over the top. Give the salad a gentle toss to mix in the seasoning. Serve immediately.
