1Preheat your grill or a skillet over medium-high heat.
Divide the lean ground beef into four equal portions and shape them into patties.
Season each patty with salt and black pepper on both sides.
Place the patties on the grill or skillet and cook for about 4-5 minutes on each side, or until they reach your desired level of doneness.
During the last minute of cooking, place a slice of cheddar cheese on each patty to melt.
While the patties are cooking, slice the large tomato and prepare the lettuce leaves.
Toast the whole wheat burger buns on the grill or in a toaster until lightly golden.
Assemble the burgers by spreading a generous amount of burger sauce on the bottom half of each bun.
Place a lettuce leaf on top of the sauce, followed by a slice of tomato.
Add the cooked beef patty with melted cheese on top of the tomato.
Finish by placing the top half of the bun on the burger.
Serve immediately and enjoy your classic burger with sauce.
