Deep Dish Pizza...Casserole?

1 lb ground beef
1 (15 oz) can chunky Italian style tomato sauce
mozzarella cheese
1/4 c. parmesan cheese (grated)
Pepperoni
Pizza dough recipe (here) or (10 oz) store bought refrigerated pizza dough

(Its best to have your pizza dough done first, I like to make it a day or two before and leave it in the refrigerator... they're just better that way) Preheat your oven to 425 degrees. Cook the ground beef in a skillet until the meat crumbles. Drain. Add the tomato sauce into the ground beef and cook until heated through. Find a 13 x 9 pan and lightly spray it with cooking spray. Unroll your dough into the 13 x 9 pan and press into the bottom, as well as halfway up the sides of the pan. (If you dont press it up the sides when it cooks it will spill its contents over the side of the dough.. and we dont want that). RIGHT on top of the pizza dough put half of the cheese (yes on the bottom) and then pour your meat/sauce mixture on top and spread evenly. Bake LIKE THIS uncovered for about 12 minutes. Place the last half of the cheese on top of the pizza and add your pepperoni to the top of the cheese. Then sprinkle with the parmesan cheese. Bake for about 5 more minutes, or until the cheese melts and the crust is browned. Adapted from mrfood.com
