Leftover sausage and peppers makes for a wonderful Italian omelette! Slice the cooked sausage into thin rounds and dice the peppers and onions before reheating in a skillet, then add 2-3 eggs beaten with a little milk, salt and pepper. When almost set, place a slice of the provolone, or any sliced or shredded cheese of your choice, on one side of the omelette and fold over to melt the cheese.
