Cut tomatoes and white onion into the smallest pieces possible (or chop in the Cuisinart). Chop green onion and cilantro. Cut peppers as small as possible but make sure to taste after adding to mix for heat factor. Juice lemons (or limes) and pour into bowl with rest of mixture. Add a generous helping of salt and pepper, then taste.
Let sit for 4 to 5 hours in refrigerator to marinate.
