All that holiday cooking can put a real strain on drains, pipes and garbage disposals.  Grease and oils are more likely to collect and clog when your plumbing is colder so do your best not to pour them down the drain. Also refrain from putting hard to grind foods/scraps and stringy substances down the disposal. Be sure to turn the disposal on before filling it with food and run cold water at least 15 seconds before and after each use.
