In a skillet break up the hamburger and brown it along with the onions and peppers in the olive oil. Once browned add in sauce of choice ( I prefer worcestershire) season with black pepper. Remove from heat place cheese over top.
Layout hamburger buns on a foil sheet top with mixture and top bun, wrap up in foil and bake in a 350 degree oven for 5 mins and serve with the sides of your choice.
