Mix the patty ingredients, and then gently form four patties of equal size, each about ¾ inch thick. With your thumb or the back of a spoon, make a shallow indentation about 1 inch) wide in the center of the patties to prevent them from puffing on the grill. Brush the tomato slices on both sides with the oil.
Brush the cooking grates clean. Grill the patties over direct medium-high heat, with the lid closed, until they are cooked to medium doneness (160°F), 8 to 10 minutes, turning once when the patties release easily from the grate without sticking. During the last 4 minutes of grilling time, grill the tomato slices over direct medium-high heat until warmed through and tender, turning once. During the last minute of grilling time, place a slice of cheese on each patty to melt and toast the buns, cut side down, over direct heat. Build each burger on a toasted bun with a patty, lettuce, grilled tomato, and sauce. Serve warm.
