8 strips bacon, cooked and broken into pieces
3 cups sliced onion
4 teaspoons olive oil
1/4 teaspoon salt
1/4 teaspoon coarsely ground pepper
1 pound lean ground beef
2 Tablespoons Worcestershire sauce
1/2 teaspoon coarse ground pepper
2 cloves garlic, minced
1 cup shredded cheddar cheese, divided
4 hamburger buns
In a large skillet cook onion in the 4 teaspoons hot oil over medium heat about 10 minutes or until golden brown; stir occasionally. Stir in bacon pieces, salt and 1/4 teaspoon pepper. Cover; keep warm.
Meanwhile, in a large bowl combine beef, Worcestershire sauce, the 1/2 teaspoon pepper, and the garlic. Divide into eight equal portions.
Shape each portion into a 4-inch diameter patty. Sprinkle half of the cheese evenly among each of four of the patties. Top with remaining patties, pressing down lightly and sealing edges well.
Grill patties directly over medium heat for 14 to 18 minutes or until done (160 degree F), turning once halfway through grilling.
Top burgers with remaining cheese the last 1 to 2 minutes of cooking time or until melted.
To serve, place patty on a toasted hamburger bun; top with bacon-onion mixture. Makes 4 sandwiches.
