If you really want to take full control of Thanksgiving dinner and cook it all yourself that is perfectly fine and your guests will love it. However, there really is nothing wrong with doing a bit of delegation and asking guests to bring a few dishes. The truth is that some people have their own specialty Thanksgiving dishes that they likely would love to show off to everyone.
So here is what you do, simply call around to your guests and discuss if they would like to bring along a side dish or perhaps a dessert. Often times your guests will be more than happy to whip up a green bean casserole or some tasty little appetizer for before the main meal. If you take care of the turkey and trimmings your guests can help round out the meal and add a little potluck convenience.
Always a good idea to let people help you in the food department
