Preheat your grill or a skillet over medium-high heat.
In a bowl, mix the lean ground beef with salt and black pepper.
Divide the beef mixture into 4 equal portions and shape them into patties.
Brush each patty with olive oil to prevent sticking.
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 tomato and red onion.
Toast the whole wheat burger buns on the grill or in a toaster.
Assemble the burgers by placing a lettuce leaf on the bottom half of each bun, followed by a beef patty with melted cheese, tomato slices, and red onion slices.
Spread ketchup and mustard on the top half of each bun.
Place the top bun over the assembled ingredients and serve immediately.
