Have your dough ready if you are making it homemade. Divide into four sections.
Preheat oven to 450F.
Heat alfredo sauce in a small saucepan. Heat tomato sauce with the defrosted meatballs in a medium saucepan.
Place the bowls upside down on a foil-lined baking sheet.
Brush the 4" bowls generously on the outside with olive oil.
Make four rounds out of the dough and form around a 4" bowl bottom; the top of the bowl can be slightly wider.
Place in the oven immediately, don't let the dough sit as it will stretch. Bake for 17 - 20 minutes or until golden brown and set. Rotate the bowls carefully once or twice for even baking.
Let the pizza bowls cool for a few minutes and then remove carefully using a fork to creep the dough away from the sides of the bowl.
Have the sauces piping hot and ready to go.
In the bottom of each bowl, place about 1/3 cup of alfredo sauce in each.
Sprinkle on a 1/4 cup of mozzarella cheese and 2 Tbsp. Parmesan to each bowl.
Add six meatballs with sauce on top of the cheese to each bowl.
Again, top with 1/4 cup mozzarella cheese and 2 Tbsp. Parmesan.
Heat in oven until cheese melts. Do not overcook.
