answer:If you can have someone almost slice through each one , with a small hinge, then simply freeze one or two per bag (sealed tightly). Then remove and toast; the hinge makes it easy to open flat while they are still frozen. If they go stale, they are stale, no matter what and suited only for bread crumbs (which are only good for mac and cheese anyway). Serving is easy; toast, smear a little cream cheese on each side , or peanut butter. I use lo-fat cottage cheese and some walnut pieces, and butter is always delicious. The classic bagel is served, toasted, with a smear of cream cheese and a very thin slice of smoked salmon (which I no longer eat).
