What To Do
1. Mix the stuffing: Combine the Horseradish Cheddar and crumbled bacon in a small bowl.
2. Form the patties: Divide the beef into 8 thin patties. Place a portion of the cheese and bacon mixture in the center of 4 patties.
3. Seal: Top with the remaining 4 patties and pinch the edges firmly to seal the cheese inside.
4. Grill: Cook on a hot grill for 5-6 minutes per side or until desired doneness is reached.
5. Assemble: Serve on toasted buns with fresh lettuce, tomato, and onion.
