Cheeseburgers With Grilled Onion
1 1/2 pounds ground beef
4 slices sweet onion (½-inch thick)
8 slices (1 ounce each) Swiss cheese
1/4 cup mayonnaise
1 tablespoon Dijon-style mustard
4 crusty rolls, split, toasted
romaine lettuce leaves
Lightly shape ground beef into four ¾-inch-thick patties. Brush onion
slices with oil. Place patties in center of grid over medium,
ash-covered coals; arrange onion slices around patties. Grill,
uncovered, 13 to 15 minutes to medium (160 degrees) doneness, or until
centers are no longer pink and juices show no pink color. Grill onions
until tender, turning occasionally. Season patties with salt and pepper
after turning, as desired.
About 1 minute before patties are done, top each with two cheese slices.
Combine mayonnaise and mustard; spread on top halves of rolls. Serve
burgers and onion slices in rolls with lettuce and tomato.
