I mix the ricotta cheese with the shredded cheese, and add seasonings to taste.  Put the cheese mixture into a casserole dish - I use a 9x12 one that is greased with Pam.  Then I evenly place the meatballs - usually 4 rows of 4. 
I sprinkle with a little parmesan, and bake it for 30 minutes (or til browned and bubbly) at 350 degrees.
It makes four servings, and I serve each with two tablespoons of the pizza sauce.

It is almost as good as the real thing - minus the bloated feeling I always had after eating the crust!!
