We cut ours into meal sized pieces and wrap them in plastic wrap. Then we put several meals in a gallon zip lock. They'll keep a couple years like that as long as you squeeze out the air every time you take out a meal and reclose it. Don't use just the zip lock. They won't prevent freezer burn. You need the plastic wrap inside. For the best air removal, use a soda straw. Zip the bag right up to the straw and suck on it to pull out the air. To finish, just pull out the straw while still sucking and snap it shut.
