If you have an oven, you can do a turkey. The wrappers on all the turkeys have directions and if you follow them even a store brand will usually come out tasty. (Take the giblets and neck out of the cavities). If you have a turkey, you got 90% of Thanksgiving licked.
My favorite stuffing is easy...EASY. A loaf of white or wheat bread (or a mix of both)ripped up in small chunks, about a cup of chopped celery, a cup of chopped onion, salt and pepper to taste, about two tablespoons of poultry seasoning, one stick of margarine and about a half cup of water. Mix it all up and shove it up the turkey's...uh...stuff the cavity from the rear...makes some tasty stuffing.
Follow the directions for making a small box of Jello (Black Cherry works best but any of the red ones will do), just before it sets up, pull it out of the fridge and mix in a can of wholeberry cranberry sauce, half cup of chopped walnuts and put it back in the fridge until it sets up firm. My favorite jello salad.
Country Crock sells tubs of mashed potatoes that nuke up in minutes and are as good as any home mashed. For that matter, they sell stuffing, sweet potatoes, and other sides the same way.
Gravy? Save the drippings from the turkey, mix some flour and water in a bowl until there are no lumps, then heat the drippings to a boil (you may need to add a little water) then stir in the flour and water mix (the folks who cook for a living call that the white wash) and boil for a good five minutes. While it is boiling add some salt and pepper. Makes good gravy.
HAPPY THANKSGIVING.
