This meatloaf is extremely juicy, and the potential variety of different flavors is as big as your imagination. Here it’s done with American cheese with ketchup and mustard on top and served with dill pickle chips. Another one might be Swiss cheese and mushroom topping.
Preheat oven to 350 degrees F (175 degrees C).
In a large bowl, combine the beef, bread crumbs, onion, eggs, salt and pepper, and mix well. Pat out meat mixture into a 14×18 inch rectangle on a piece of wax paper. Spread cheese over the meat, leaving a 3/4 inch border around the edges. Roll up jelly roll fashion to enclose the filling and form a pinwheel loaf. Press beef in on both ends to enclose the cheese. Place in a 10×15 inch baking dish.
Bake in the preheated oven 1 hour, or until internal temperature reaches 160 degrees F (70 degrees C)
