Quick philly cheesesteak sandwiches

1. Melt the butter and oil in a medium-sized skillet set over medium heat. Add onions, peppers and mushrooms. Cook, stirring often, until vegetables begin to soften. Season with salt and pepper and continue to cook just until the onions begin to brown around the edges.

2. Split the meat equally between rolls, top evenly with cooked veggies, top with cheese. Roll each prepared sandwich tightly in foil. Bake @450ºF for 10 minutes, or until cheese has melted and sandwiches are heated through.

3. Leave any leftovers wrapped in foil and bake in the oven to reheat.
