A number of years ago (2002, I think), my late brother and his wife hosted Thanksgiving at their modest home. Everything was prepared by Publix! There were some logistical problems determining what got heated up at what temperature in a limited-size oven, but the food was excellent, and we managed to overcome the timing issues quite easily.
I have no idea how much everything cost, but I know that my brother was well-satisfied!
Worth inquiring.
