My son made this the other night. It was devoured in nothing flat. Delicious and simple. Feel free to add whatever hamburger toppings you want over the top. The whole idea is a cheeseburger but made from mac'n'cheese and meat filling instead of a bun and a patty.
3 boxes macaroni and cheese mix, made as per directions OR 8 c. homemade mac'n'cheese
1 lb. hamburger
1 medium onion, chopped
1 14.5 oz can diced tomatoes (we used basil, garlic & oregano flavor)
1/4 c. ketchup
1 t. prepared mustard
Make mac'n'cheese as directed. Set aside where it will stay warm.
Saute onions in large frying pan just until softened. Add hamburger. Cook until meat is completely done and crumbled. Add tomatoes, ketchup, and mustard. Turn heat to low. Simmer for 10-15 minutes until everything is hot and blended.
To serve: Scoop a serving of mac'n'cheese onto a plate. Add a large spoonful or two of meat mixture on top. Add whatever hamburger toppings you want - shredded lettuce, sliced tomatoes, pickles, onions, etc.
