Pre-preparing certain things

Dice Bell peppers                                                                             Dice Celery

Dice Onions Never - ever put an onion with your other veggies (unless the onion is in a zip lock bag or sealed bowl) because it will make the other veggies rot faster.

Put bags of chopped veggies in the crisper (bottom drawer of your refrigerator).  Sautee veggies the day you prepare the stuffing and/or dressing.
