Cut bread in length wise, being sure to cut bread through. Place bread in toaster oven to heat and brown the bread. Cut sausage in half lenghtwise and cook in skillet until done. Cook peppers and onions in skillet until soft. Place both bread halves on baking pan. Place sausage on one bread hal and cover with peppers and onions. Pour marinara sauce on onions, sprinkle with cheese and bake both bread halves for 3-4 minutes until cheese melts. Remove from oven, put top on bottom and cut in half. Mmmmmmm.
