remember seeing a program like this when I was young and struggling with food budget, helped me a lot, and both daughters have wished for something similar:
how to choose low cost cuts of meat, cook and cut up for several meals, how to prepare, cook, cut up, freeze, serve, what foods they go with, saving time and money.
for instance how to get 4 meals for 4 out of a whole chicken, out of a chuck or round roast, out of a picnic ham, etc.
also how to make stocks, soups and breads, had a cookbook called “soup and bread book” or simillar that I used all the time, gave it away, but the habit of always having stock on hand makes me a better cook than I would be normally. It also had a lot of “desperation” recipes, so I can usually come up with a tasty, nutritious meal out of anything on hand in the pantry or freezer, at low cost. I think today a show like this would be a hit.
I also think the Catholic ethnic cooking show would be hit. our diocesan newspaper used to have such a feature, Italian recipes around St. Joseph day, pre-Ash Wed recipes, lenten of course, ethnic Christmas, wedding or other special day recipes.
