Make Sure To Rinse And Drain The Beans, If You Are Using Canned Beans. In A Large Bowl, Combine The Beans, Corn, Onions, Jalapeno Chile Peppers, Tomatoes, Avocado, Cilantro, Basil, Lime Juice And Olive Oil. Add Sugar And Salt And Pepper To Taste. (The Sugar Will Help Balance The Acidity From The Tomatoes And Lime Juice.) Chill Before Serving.
