Food saver - When it comes time to pack up the Thanksgiving leftovers, old and mismatched Tupperware containers have nothing on the FoodSaver line of food packaging systems. FoodSaver also has sturdy plastic containers that can be used with a vacuum to get the contents airtight. Seal your leftovers in airtight plastic bags that won't take up as much room in the fridge, which quickly becomes prime real estate during the holidays. Though you may want to skip that technique for the mashed potatoes and pie.
