Have you ever been to the Hillbilly Housewife website? The site has tons of ideas and recipes for frugal, home-cooked meals. Some of the recipes would need to be adapted if you are very health-conscious, but the site is invaluable for help and encouragement for low-budget homemade cooking. There is a new Frugal Holiday Recipes section that is definitely worth checking out.
Other highlights include the Emergency $45 Menu and Emergency $70 Menu; Magic Milk Shakes; Homemade Convenience Foods; and Beginner's Bread.
The site's previous owner also has a site called An Old-Fashioned Education, which is a free Charlotte Mason style curriculum.
