Using long-handled tongs, moisten a paper towel with cooking oil and lightly coat the grill rack. Grill burgers, covered, over medium heat or broil 4 in. from the heat for 5-7 minutes on each side or until a thermometer reads 165° and juices run clear.

Place on buns; top each with about 1/4 cup sauce. Serve with the lettuce, cheese, tomato and onion if desired.
