Remove seeds and membranes from jalapeno and banana peppers if desired (for a less spicy salsa). Dice peppers and place in a bowl; add remaining salsa ingredients and mix well. Cover and refrigerate until ready to serve. Form the sausage into six patties; cook in a skillet over medium heat until meat is no longer pink. Place each on an English muffin half; top with 1 tablespoon salsa and a slice of cheese. Cover with other muffin half. Serve
