1/4 cup shredded Cheddar cheese
1/4 cup Gruyere cheese
1 pound 90% lean ground beef
1 tablespoon worcestershire sauce
1 1/2 teaspoons paprika
1/4 teaspoons freshly ground pepper
Preheat grill to medium high or preheat the boiler.
Combine cheese in a bowl.
Gently mix beef, worcestershire, paprika and pepper in a large bowl, preferably with your hands, without overworking. Shape into 8 thin, 4 inch wide patties. Mound 2 tablespoons of the cheese mixture on each of 4 patties, leaving a 1/2 inch border. Cover each with one or the remaining patties. Crimp and seal the edges.
To grill: Lightly oil the grill rack. Grilled the stuffed patties over medium-high heat, about 4 minutes per side for medium-well. (Be sure not to press the burgers as they cook or they'll split open and the cheese will ooze out.) To broil: Cover a broiler pan with foil and coat with cooking spray. broil the stuffed patties in the upper third of the oven, about 4 minutes per side for medium-well. In either case, let the burgers stand for 5 minutes before serving.
