Egg 'n Muffin

Preparation : In a medium nonstick skillet coated with nonstick spray, cook the pepper and onion mixture over medium-high heat until the onion is tender, 2 or 3 minutes. Lower the heat to medium. Add the egg substitute and mustard and cook, stirring occasionally, until the egg is cooked through, about 2 minutes. Remove from heat and stir in catsup. Spread the mixture evenly on open, untoasted English muffin halves. Sprinkle with cheese. Toast in toaster oven or under broiler until cheese is just melted and muffins are warmed.
