We’ve been there. I’d find a small turkey, and pick out a couple of "different" sides you’d both like to try. It’s good practice for when you’ll be doing the entertaining.
And (hopefully) you’ve got the whole long weekend to eat and figure out what to do with the leftovers. I make a soup stock out of the carcass, and we usually freeze some meat in gravy (leftover, if any, or prepared from the stock) with veggies to make a pot pie or two later.
Conrats and enjoy!
