we recently visited with my dad, and noticed that after breakfast one day he took some ziploc bags out of the freezer and put them into the fridge to thaw. one of the bags contained 4 slices of bread, the others had an amount of deli meat and cheese appropriate for one sandwich each. he said he got tired of throwing out unused portions of sandwich fixins and so started putting the ingredients into ziploc bags and freezing them. then later, on the day he’ll be eating a sandwich for lunch, he takes what he needs out of the freezer and puts it into the fridge to thaw. by lunch things have thawed well enough, and then he zaps the bread in the microwave for a fresh-bread experience. what a cool idea! no wasted bread, no lingering piece of ham or cheese in the fridge.
