After they have cooled a bit, I just label a freezer bag with date and instructions (heat 1 1/2 minutes wrapped in a paper towel) that's for 3, longer for more, less for less..you get it. Place them in the bag staggered and push as much air out you can without squishing them. Lay flat in freezer. They stay good for 3-4 months!
