1 lb. Steak, cut into strips
1/2 Onion, sliced
1/2 Green Pepper, sliced
1/2 Red Pepper, sliced
2 Tbsp. Worcestershire sauce
Salt & Pepper
4 Hoagie Buns

Preheat oven to 350 degrees. Brown beef in large non-stick skillet for about 5 minutes or until almost fully cooked. Add sliced onion and green pepper and Worcestershire sauce. Sautee until veggies are crisp-tender and meat is fully cooked.
Season mixture to taste with salt and pepper. Open up hoagie buns on a cookie sheet and spoon meat mixture evenly onto each sub. Top with slice of cheese.
Bake in oven for about 5-10 minutes, or until cheese is melted and bun is toasted. Remove from oven, add Miracle Whip to other side of sub bun. Close sub, and enjoy!
