Step 1

In a bowl, gently stir together tomatoes, avocados, onion, and garlic. I also squirted some lime juice on it to give it more flavor and to keep the avocados from browning as quickly. Mix in cilantro.

Step 2

Gently stir in olive oil and vinegar. Then stir in feta. Salt and pepper to taste. Cover, and chill for at least an hour. Serve with tortilla chips. *It's is best to make it close to when you are serving it.
