Brew Burgers

Brew Sauce:
1/4 cup Heinz 57 Sauce
1/4 cup beer

In 1-cup glass measure, combine ingredients. Microwave on HIGH 1 to 1 1/2 minutes until bubbly; set aside.

Burgers:
1 1/2 pounds ground beef
1 large sweet onion, 1/2-inch slices
4 slices Swiss cheese
4 crusty white or whole wheat rolls, split
Lettuce

Shape ground beef into four 3/4-inch thick patties. Place onion slices on grid over medium, ash-covered coals. Grill onions, uncovered, 5 minutes.

Add patties; continue to grill, uncovered, 1 to 15 minutes or until onions are tender and burger centers are no longer pink, turning occasionally. Season burgers with salt after turning, if desired. Approximately 2 minutes before burgers are done, brush generously with sauce mixture; top with cheese.

Line bottom half of each roll with lettuce. Top each with burger, grilled onion and sauce. Close sandwiches.
