In a small bowl, mash the avocados. Stir in the pineapple, mango, peaches, jalapeños, red onion, cilantro, lime juice, lemon juice, garlic, salt and pepper. Gently stir all of the ingredients together. You may want to add more jalapeño peppers if you desire the guacamole to be spicier. Serve with tortilla chips.
Makes 5-6 cups of guacamole
