Freezing instructions: After cooking ragout, place in a large heavy-duty zip-top plastic bag. Cool completely in refrigerator; freeze for up to 1 month. To reheat, place bag in a large pot of boiling water (do not unseal bag). Cook 15 minutes or until thoroughly heated. Remove the bag from water using tongs. While ragout is reheating, grate the cheese, and cook the pasta according to package instructions, omitting salt and fat.
