There are loads of recipes for this floating around the net. I tried one of them and to be honest it tasted like spaghetti with pepperoni. So I tweaked it. I dont post recipes much cause I am more of a little bit of this and a little bit of that kinda gal. But here ya go.
Ingredients:
pasta
spaghetti sauce with browned hamburger in it
shredded cheese
pepperoni
Optional ingredients:
olives, mushrooms, onion, bell peppers, ham, sausage
Make however much spaghetti and sauce you normally make for your size family. Then in the sauce add some cool stuff like finely chopped mushrooms, black olives, ham, sausage, onion. The more pizza toppings you add the more 'pizza-y' it will taste. ADD SALT. Sometimes spaghetti can have a little bit of a sweet taste, but just a little bit of salt tends to help.
Once your noodles are cooked and your sauce tastes the way you like mix them together. Put half of the noodle mixture in a casserole pan. Cover in shredded cheese (I used a combo of half empty bags we had in the fridge. Mozzarella is always a good choice.) Then cover in pepperoni. Repeat this paragraph.
Bake for 15 min at 350 degrees.
