This was such an easy way to make a cheeseburger – it would also work great with meatballs.
1 lb. ground beef
1/2 chopped red onion
1/4 cup breadcrumbs or smashed crackers (you can use gluten free crackers if you like)
1/4 tomato sauce
Garlic powder, salt & pepper to taste
Shredded cheddar cheese
Preheat the oven to 375. Grease a muffin tin.
Combine all ingredients, except for the cheese. Fill each muffin tin with the meat mixture.
Cook for about 35 minutes or until the meat is firm. Top with the cheese and cook for another 5 minutes.
Serve with ketchup and mustard.
