Oil, for grill

salt and freshly ground pepper
4 slices white cheese
4 large bakery sandwich rolls
4 teaspoons mayonnaise
1 beefsteak tomato,
1/2onion, cut into 1/4-inch rings
4 lettuce leaves, such as green-leaf
Directions
Preheat grill to medium.brush grates with oil.
Gently form beef into four 1-inch-thick patties, about 3 inches in diameter. Make an indentation in the top of each patty. Generously season both sides with salt and pepper.
Grill burgers 3 minutes. Flip, top with cheese, and grill 5 minutes for medium-rare. Toast rolls face-down on grill until just lightly charred, about 25 seconds. Spread them with mayonnaise if you're a condiment die-hard though our food editors swear you won't need it.
Sandwich burgers in with tomato, onion, and lettuce.
