Hmm, good question! Sorry, but I've never had their Thanksgiving meals... their other prepared food that I've had from their hot bar has been very good, though, and they seem to be quite conscious of using quality, wholesome ingredients. Hope that helps!
I tried it one year and it was ok. Some things were over seasoned (sweet potatoes with cinnamon) and others were kinda bland (gravy). But the one thing that I love (and admittedly not very healthy) is crispy turkey skin and the turkey skin was rather soggy. Most def does not taste like a home cooked dinner.
My ex bf has it almost every year. You gotta order early because everything sells out fast. I would say Whole Food's Thanksgiving sets are pretty tasty, and no hassle(that's the best part), ^_^. Turkey, Cranberry Sauce, Mashed Potatoes, Stuffing, gotta get the Pumpkin pie!!!
I used to order my fresh turkeys from them every year, but the turkeys were always obviously frozen. I switched to Fresh Market for my turkey. I have always enjoyed Whole Foods other prepared foods though, so I'm sure their Thanksgiving meals are wonderful.
I have ordered other holiday foods from WF and have liked it. You can probably specify if you want something different (like..turkey cooked a certain way, or sliced, or turkey seasoned less/more). I have found them to be pretty accomodating as long as you spell it out clearly ahead of time.
