I love this recipe because it has directions if you freeze it!
26-oz jar marinara or pasta sauce
Two 13-oz packages cheese ravioli
1 1/2 cups shredded part-skim mozzarella cheese
1. Spread 1/2 cup marinara sauce in the bottom of a foil baking pan. Spread 1 package of ravioli in a single layer on sauce. Top with 1 cup of sauce and 1/2 cup mozzarella. Layer the second package of ravioli on top, then 1 cup sauce and 1 cup mozzarella. Cover pan with foil and freeze until ready to use, or bake covered at 400 degrees for 30 minutes, then uncovered for 5 to 10 minutes.
To bake frozen lasagna: Preheat oven to 400 degrees. Bake, covered, for 1 hour. Remove foil and continue baking until cheese is melted and starting to brown, and inside middle is hot, about 25 minutes more.
