A delightful twist on the classic cheeseburger, this meatloaf sandwich is packed with flavor and perfect for any meal.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
In a large mixing bowl, combine the egg, tomato sauce, oats, onion, salt, and pepper.
Mix gently to avoid overworking the meat, which can make it tough.
Add the ground beef to the mixture and combine until just mixed.
Use your hands for even mixing, but don't overmix.
Press the mixture evenly into an ungreased 13x9-inch baking dish.
Ensure an even thickness for uniform cooking.
Bake uncovered for 30-35 minutes or until the internal temperature reaches 160°F (71°C).
Check the temperature at the center for accuracy.
In a small bowl, mix the mayonnaise and ketchup.
Adjust the ratio to your taste preference.
Spread the sauce over the baked meatloaf evenly.
Use a spatula for a smooth application.
Cut the meatloaf into rectangles and top each with tomato slices, cheese, and bacon.
Layer the toppings neatly for an appealing presentation.
Place the topped meatloaf pieces on a baking sheet and broil for 2-3 minutes until the cheese melts.
Keep an eye on the broiler to prevent burning.
Serve the meatloaf pieces on hoagie rolls and enjoy.
Serve with a side of fries or a salad for a complete meal.
