The first, best tenet of the religion of not starving is not to throw calories away. Eat them or freeze them. Meat scraps left on your plate when you're done with your steak can go in the stock bag. Peels and any oddities you cut off your vegetables as you prepare them for ingestion can go in the stock bag. Everything goes in the stock bag. When the stock bag fills up, make stock and make soup with the stock. Eat the soup. Begin again.
I got some books on freezing at a garage sale for 5 cents each. They show you how to wrap things and stuff and tell you handy tips like for instance, "don't freeze lettuce." Some absolutely fascinating recipes for desserts, since these came out in the 50s. While I can still afford to shop, I should experiment with these desserts and report. Okay: that's what I'll do!
