Inside-Out Cheeseburgers

Ingredients:	1/4 cup shredded Cheddar cheese 1/4 cup shredded Gruyere cheese 1 pound 90%-lean ground beef 1 tablespoon Worcestershire sauce 1 1/2 teaspoons paprika 1/4 teaspoon freshly ground pepper
Directions:	Preheat grill to medium-high or preheat the broiler. Combine Cheddar and Gruyere in a small 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 of the remaining patties. Crimp and seal the edges closed. To grill: Lightly oil the grill rack (see Tip). Grill 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.
