Roll out refrigerated pizza dough on to a cutting board. Use rim of a glass or round cookie cutter to make circles in the dough that fit into each muffin tin hole.
Spray muffin tin with non stick spray and push circles of dough into each tin hole so they come up a bit on the sides and cover the bottom.
Preheat oven to 400 degrees and cook dough for 4 minutes, just so it stiffens up a bit. Remove from oven and spoon sauce, cheese and toppings into each one.
Bake again for another 6 minutes or so until the edges of the dough are browned and cheese is melted.
Remove, allow to sit for 2 minutes in the pan and use a tbsp to scoop each one out.
