So far, they have done a story with a Spanish chef, a Chinese-American chef (one of my favorite celebrity chefs, Ming Tsai), a former Navy chef, and the Neelys, who have a Food Network show specializing in Southern style home cooking. The last one, the Neelys, kind of dismay me. While the others presented chickpea stew with spinach, upscale fried rice, or skate with potato gnocchi (all foods based on mainly unprocessed ingredients), they did macaroni and cheese. In the interview, they justified the choice because it was filling, and that it was nutritious because it had meat in it. In the form of bacon.
I consider that being nutritionally shortsighted.
Personally, I think I can do pizza soup for four for much less than $10. Certainly enough left over for some slices of pepperoni.
