I didn't realize that the Thanksgiving in One Pot was an actual Semi-Ho recipe, but I haven't seen every episode. The description kind of reminds me of a segment on Guy's 'Diners, Driveins, and Dives' show where he visited a place (in a college town, IIRC) where they made a 'Thanksgiving Dinner' waffle dish. It was a large waffle made of stuffing, topped with sliced turkey, mashed potatoes, and cranberry relish. I'm a little ashamed to say that it actually sounded and looked pretty tasty (but I love sweet and savory together, so that was probably the reason).
I guess the closest I've come to Semi-Ho cooking is that I'll occasionally use a boxed cake mix or bagged cookie mix as a base for a recipe. However, the rest of the ingredients are always 'good' (like fresh fruit, nuts, good chocolate, real whipped cream, etc.). I would prefer making the cake/cookies from scratch, but I don't always have time.
