1 to 2 tablespoons finely chopped sweet red pepper
6 submarine sandwich buns (about 6 inches), split
In a large skillet, cook sausage and onion over medium heat until the meat is no longer pink; drain. Remove with a slotted spoon and keep warm.
In the same skillet, cook and stir the eggs over medium for 6-7 minutes or until nearly set. Add mushrooms, peppers and the sausage mixture. Cook until eggs are completely set and mixture is heated through. Serve on buns.
