To me, there's no economy in cutting good nutrition out of the budget. In 30 years of marriage, of course we've had some tight times--but even so, I've never resorted to serving my family lunch meat--it's loaded with chemicals and fat.
Few things are cheaper than buying a whole turkey--and you get so many meals out of one--dinners, sandwiches, a big kettle of soup. A smart cookie could feed a family for a week on one turkey. I cannot imagine that it's even cheaper $$$wise to buy any kind of lunchmeat over a turkey. And if you get the free ones all the stores offer at Christmas and Easter.... well, you can't beat free.
And in my book, vitamin pills and dr's visits cost more than fresh fruit, vegetables and quality meats.
