Directions:

Combine beer and steak sauce in a 1 cup glass measure. Cover and microwave on HIGH for about 1 1/2 minutes or until bubbly.

Lightly shape ground beef into four 3/4- thick patties. Place patties in center of grid over medium, ash-covered coals. Place onion around patties.

Grill, uncovered, 13 to 15 minutes to medium (160 degrees F) doneness, until no pink remains and onions are tender, turning once. Season with salt.

About 2 minutes before patties are done, brush generously with sauce, then top with cheese.

Serve burgers and onion in rolls with lettuce and sauce.
