Preparation

• 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 become tender.
• If using mushrooms, add them next and cook for an additional 3 minutes.
• Push the softened veggies to the side of the skillet, add the ground beef, and cook until no longer pink, about 5-7 minutes.
• Stir in the garlic powder, Worcestershire sauce, salt, and pepper. Mix thoroughly for about 2 minutes.
• Reduce the heat to low, place a slice of cheese over the beef mixture, and cover the skillet. Allow the cheese to melt, about 2-3 minutes.
• 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.
• Consider toasting the rolls lightly before assembling for added texture.
