pizza dough (a little bigger than a baseball for a 12 inch pizza). Most grocery stores carry pre-made pizza dough, look for it in the bakery department.
2 Tbsps of pizza sauce (sauce in the jar is just fine, on the pasta isle of your grocery store).
1 handful of mozzarella cheese (add other cheeses if you want!).
A few Tbsps of all purpose flour so things don’t stick.
2 Tbsps of olive oil.
Toppings (whatever you want!)
Cookie sheet (with no sides).
Grilling tongs and/or spatula.
Brush for your olive oil.
(optional) a pizza stone for the grill
