Manicotti with Cheese and Spinach

I got this recipe from Kara West when I babysat her kids in college. It's very simple and really good! It's one of the first recipes I made for Adam too and he has always liked it. It's a meatless dish but I've added italian sausage to the cheese mixture or used a meat sauce on occasion... you know how guys like meat!

14 pieces of uncooked Manicotti or a box of jumbo shells

1 15oz container part-skim ricotta cheese

2 c. shredded mozarella

1/4 c. grated parmesan cheese

1 pkg. frozen spinach, thawed

1/2 tsp. salt

1/4 tsp. pepper

3 c. spaghetti sauce (any flavor but I like garlic parmesan)

-Cook pasta in boiling water for 6-8 minutes, drain well and cool on wax paper.

-Preheat oven to 350 degrees.

-In large bowl, stir together cheeses, spinach, salt, and pepper.

-Spoon mixture into cooled pasta tubes or shells.

-Spready thin layer of sauce on bottom of 13x9x2 baking dish and arrange pasta in single layer over sauce. Pour remaining sauce over pasta and cover pan with foil.

-Bake for 40 min; remove foil and bake for 15 more min. or until hot and bubbly.
