Preparation Steps

• In a large skillet, add a drizzle of olive oil and heat over medium-high.
• Add the sliced onions and bell peppers. Sauté for about 3-5 minutes until they are tender. If using, add mushrooms and cook for an additional 3 minutes.
• Push the vegetables to the side of the skillet and add the ground beef to the pan. Break apart and cook until no longer pink, about 5-7 minutes.
• Stir in garlic powder, Worcestershire sauce, salt, and pepper. Mix everything together properly for about 2 minutes.
• Reduce the heat to low. Place a slice of cheese over the beef mixture. Cover the skillet with a lid and allow the cheese to melt, about 2-3 minutes.
• While the cheese is melting, slice the hoagie rolls lengthwise without cutting all the way through.
• Once the cheese has melted, spoon the beef and vegetable mixture into each roll.
• Optionally, toast the rolls for added texture before serving.
