Creating Cheeseburger Pizza is easy when you follow these steps:

1. Preheat Your Oven: Preheat your oven to 425°F (220°C).
2. Cook the Beef: In a skillet over medium heat, add olive oil. Once hot, add the ground beef. Season with garlic powder, onion powder, salt, and black pepper. Cook until browned, about 5-7 minutes. Drain excess fat.
3. Prepare the Pizza Crust: Roll out your pizza crust on a floured surface if necessary, then transfer it to a pizza stone or a baking sheet lined with parchment paper.
4. Add Pizza Sauce: Spread the pizza sauce evenly over the crust, leaving a small border around the edges.
5. Layer the Cheese: Sprinkle mozzarella cheese generously over the sauce, followed by the cheddar cheese.
6. Add the Beef: Evenly distribute the cooked ground beef over the cheese layer.
7. Top with Vegetables: Add diced tomatoes, pickles, onions, and olives (if using) on top of the beef.
8. Bake the Pizza: Place the pizza in the preheated oven and bake for 20-25 minutes, or until the crust is golden and the cheese is bubbling.
9. Cool and Slice: Once baked, remove the pizza from the oven and let it cool for a few minutes. Slice into wedges.
10. Add Final Touches: Drizzle mustard over the pizza if desired, and garnish with fresh lettuce leaves before serving.

These steps will guide you in creating a delicious Cheeseburger Pizza that everyone will love.
