You use only half of the avocado and dice it up in little cubes, then mix it with the rest of the thinly chopped ingredients like the onion, bell peppers, green onion, and parsley. Then add all the other ingredients like the vinegar, olive oil, salt, pepper and lime juice. Then take the remaining avocado and blend it or process it, along with 3 tablespoons of the previous mix. Finally, combine everything together. You can garnish with a little bit of diced tomatoes on top.
