Creating this Cheeseburger Pizza can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Cook Beef: In a skillet over medium heat, add the ground beef and diced onion. Cook until the meat is browned and the onion is translucent, about 5-7 minutes.
3. Season Beef: Drain excess fat, then sprinkle in garlic powder, salt, and black pepper. Add ketchup and mustard, mixing well. Cook for another 2 minutes.
4. Prepare Crust: Roll out your pizza crust on a baking sheet or pizza stone, ensuring it is evenly shaped.
5. Add Beef Mixture: Spread the cooked beef mixture evenly over the pizza crust.
6. Add Cheese: Sprinkle the shredded cheddar cheese generously over the beef.
7. Bake Pizza: Place the pizza in the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly.
8. Add Toppings: Remove the pizza from the oven. Immediately add pickles, diced tomatoes, and shredded lettuce on top.
9. Cool: Let the pizza cool for about 10 minutes before slicing.
10. Garnish: Optionally, sprinkle sesame seeds over the top for an extra touch.
