The only thing better than your classic cheeseburger is a burger stuffed with mac and cheese! Take this one for example...

Mac and Cheese-Stuffed Burgers

Combine beef, Worcestershire sauce, garlic, and pepper; form mixture into 8 (1/2-inch-thick) patties.

Spoon 3 tablespoons macaroni and cheese in the center of 4 patties; sprinkle with cheese. Top with remaining patties; pinch edges together all the way around to seal filling inside.

Prepare a charcoal or gas grill with a greased grill rack for direct cooking over medium heat (350 degrees). Grill patties 10 to 12 minutes or until well-done (165 degrees), turning once halfway through grilling. Place onion rings on grill during the last 5 minutes of cooking. Grill until golden brown, turning once.

Spread cut sides of buns with mayo. Layer lettuce, beef patties, pickles, and onion rings on bun bottoms. Add bun tops.
