Preheat a grill or skillet over medium-high heat. Divide the ground beef into four equal portions and shape each into a patty. Season with salt and pepper.
Cook the patties for about 4-5 minutes per side until fully cooked and juices run clear. In the last minute of cooking, place a slice of cheese on each patty to melt.
While the patties cook, toast the burger buns until golden brown. Spread marinara sauce on the bottom buns and prepare the pizza toppings.
Assemble the burger by placing a cooked beef patty on each bottom bun, add extra marinara sauce, sprinkle with pizza toppings, and top with the remaining bun. Serve immediately.
