Pizza Sliders

Position the oven rack approximately six inches away from the heat source and set it to broil mode. Heat up your oven's broiler.

Arrange bun halves, with their crust sides facing downwards, onto a baking sheet. Subject the buns to broiling until they are lightly toasted, around 1 minute. Keep a close eye on them as they can easily burn. Remove the buns from the oven and set them aside.

Heat your oven to 350 degrees Fahrenheit (175 degrees Celsius).

Cook the ground beef in a large skillet over medium heat, stirring occasionally, until it is browned and crumbly, roughly 10 minutes. Drain any excess grease that may accumulate during cooking. Add the onion to the beef mixture and continue to cook, stirring occasionally, until the onion becomes translucent, approximately 5 minutes more. Introduce pizza sauce, Parmesan cheese, Italian seasoning, garlic powder, paprika, onion powder, and red pepper flakes into the mixture. Bring the ingredients to a boil before allowing them to simmer for 10-15 minutes, stirring frequently, in order to blend the flavors.

Spoon the pizza sauce mixture over the buns on the baking sheet; top each bun with around 1/4 cup of mozzarella cheese.

Place the buns in the preheated oven and bake until the cheese is bubbly and lightly browned, approximately 10 minutes.
