Cut each pepper in half and remove seeds. Fill each pepper with the chopped tomato, and drizzle olive oil over the top of the tomatoes.
Add a slice of mozzarella on top of the tomatoes, and then add a dash of salt and pepper and a sprig of basil.
Place the filled pepper halves on a hot grill, but not directly over the flame. Cover and grill for about 30 minutes, or until the pepper is soft.
Use red, yellow, or green bell peppers, or Italian or Hungarian sweet peppers.
