Wampus-one year I was told at the last minute I had about 18 people showing up on Christmas Day Night meal. I cooked a tenderloin as mentioned above, sliced it really thin and family made mini sandwiches with Kings Hawaiian rolls. Horseradish sour cream, chipotle mayonnaise + normal condiments. Served it with a German potato salad. There were other things there like Marie Callander's apple pie and Blue Bell ice cream.
Bottom line, tenderloin can be a pretty cheap way (other than olive loaf and white bread) to feed the masses an elegant meal-when you get surprised at the last minute. Tenderloin on a paper plate made for a memorable meal
