First of all, the most important part of Thanksgiving has completely fled unity, so forget everything else and get good food. As an amateur cook I recommend the following.
Mapled Ham: Very time consuming. Unbelievably good if prepared correctly.
Turkey with Gravy: A popular, basic food for the season.
Whipped Potatoes: Basically mashed potatoes, but you can use an electric beater instead.
Cranberry Sauce: Typical Thanksgiving sauce.
Horseradish Sauce: Good for added flavor, do not use in excess.
Sawdust pie: VERY good. on foodnetwork.com
Apple Pie: Many variations. I do not recommend adding raisins.
Pumpkin Pie: Buy it at a store, it is far to difficult to make fresh, and canned pumpkin is much easier.
