Pizza Burgers

1. Preheat your grill or grill pan to medium-high heat.
2. In a large mixing bowl, combine the ground beef, pizza sauce, finely chopped onion, finely chopped green bell pepper, Italian seasoning, garlic powder, salt, and pepper. Mix until well combined.
3. Divide the mixture into 4 equal portions and shape each portion into a burger patty.
4. Grill the burger patties for 4-5 minutes on each side, or until they're cooked to your desired level of doneness.
5. During the last 2 minutes of grilling, place a slice of mozzarella cheese on top of each burger patty and allow it to melt.
6. While the burgers are grilling, lightly toast the hamburger buns on the grill.
7. Once the burger patties are cooked and the cheese is melted, remove them from the grill.
8. Assemble the pizza burgers: Place each burger patty on a toasted hamburger bun. Top with additional pizza sauce, pepperoni slices (if using), sliced black olives (if using), and sliced mushrooms (if using).
9. Serve the pizza burgers hot, with your favorite side dishes such as French fries, potato chips, or a side salad.

Enjoy your delicious homemade pizza burgers, packed with the flavors of pizza and juicy beef patties!
