For Thanksgiving, I tend to stick to the foods that we don’t have very often: Turkey, stuffing, cranberry sauce, some sweet potatoes, sometimes a fruit salad. I am not a great cook, but like to make Thanksgiving dishes “from scratch”.
But it sounds like you are doing very well with your food choices and diet!
I just know that protein is not fattening, you can eat as much as you can.
There is nothing wrong with breaking your diet for a special occasion like Thanksgiving, as long as you get right back to it afterwards.
