I get an email every day from Mr. Food.com and a lot of them sound very good. This one is an easy version of lasagna. I'm not saying it's cheap, but I'm going to try it sometime.

Serves: 8
Cooking Time: 55 min
Ingredients
2 (26-ounce) jars spaghetti sauce
1 (9-ounce) box frozen chopped spinach, thawed, squeezed dry
2 (22-ounce) bags frozen square cheese ravioli
3 tablespoons grated Parmesan cheese
3 cups shredded mozzarella cheese
Instructions
Preheat oven to 375°F.

Spread 1 cup spaghetti sauce on bottom of a 9" x 13" baking dish. Sprinkle one-third of spinach over sauce, layer one-third of ravioli on next, then sprinkle with 1 tablespoon Parmesan cheese. Pour 1 cup spaghetti sauce on top then evenly distribute 1 cup mozzarella cheese.

Repeat layers 2 more times, ending with sauce.

Cover and bake 50 to 60 minutes, or until hot in center. Remove cover and sprinkle with remaining 1 cup mozzarella cheese. Heat 5 more minutes, or until cheese is melted. Let sit 5 minutes before slicing and serving.
