Tonight's easy for me.
We have a wonderful tradition of getting together with my brother's family and we eat shrimp cocktail, shrimp scampi, filet mignon, twice baked potatoes, and...um...squirrel.
Never had the squirrel before! But basically I eat a small portion of all that meat equaling only a slightly larger than normal portion of protein for me.
And I don't drink.
However, yes, all holidays are food events to get through. I have survived over a year now by passing on those things that are just sort of good, like pumpkin pie and rolls, and indulging in tiny portions of that which I really love. So I may have a table spoon size portion of mashed potatoes, or one sausage/cheese/cracker, or two chips with dip. I concentrate on filling up at these events with the veggie trays or salad.
