I make this from site so I am putting in what I use most of the time. My friends back home used have me make this or lasgna for pot lucks all the time so I guess you can say that it is a hit. Plus it is one of those meatless dishes that please just about everyone except for a vegan.
Preheat oven to 350. Spray Casserole dish to reduce sticking.
Boil pasta according to the package. Drain.
In a metal bowl mix half the package of mozzarella, 8 onces of ricotta cheese, pasta, and one jar of sauce.
Add to casserole dish and cover with the rest of mozzarella. (Note you can add mushrooms to this - I Used to for some of the group I was friends with - but I prefer it as is or with some pepperoni thrwon in on days I want some meat!)
Bake for 30 minutes or until bubbling and golden on top.
Serve with additional sauce on the side and grated cheese. Enjoy!
