Well...we have Thanksgiving at my inlaws. I usually bring plenty of bottled water and Diet soda so I stay away from all of the food.
I eat some of the white meat roasted turkey and nibble on the veggie tray-and I always bring a reduced calorie dessert with me-so I can indulge in a serving of dessert without blowing my plan. Last year I made sugar free crustless pumpkin pie, the year before I brought a tray of fresh cut up fruit. Not sure what I am going to make this year...I will have to look through my recipe books.
