Cook a package of large shell pasta according to the package directions. Rinse them in cold water as soon as you pull them out of the pot so that you can actually handle them, then spread out on a large plate misted with PAM so that they don't stick. In the mean time, thaw a package of 32 meatballs. Pour a half cup of sauce from a quart jar into the bottom of a 9x13 pan and spread it around. Have your helpers help you stuff a meatball inside each shell, and nestle them all into the pan. Next time I make this, I will toss the meatballs with some of the sauce before doing this. Messier, yes, but I think it'll really improve the flavor of the end product.
Drizzle the remaining sauce over the top of all the shells, then have your helpers spread cheese on top. I used about 2 cups. You could use less, but would you want to?
