Serve this lively dip with tortilla chips or on top of chili (try it with Chili Con Carne). If you want to make it a day ahead, be sure to press plastic wrap directly on the surface of the guacamole.
Halve avocados, and remove pits. Score flesh into cubes with a small sharp knife, and scrape into a bowl. Stir in lime juice, lemon juice, tomatoes, onion, chile, and garlic. Season with salt and pepper.
