I assume it's largely to promote the use of crops grown and animals raised in the state. Some examples:
- Alaska
- California (plus our Department of Education has their own page of recipes—though since that list is geared for school lunch programs, the yields on those recipes are on the order of dozens of servings)
- Idaho
- Washington
- West Virginia (several cookbooks plus other publications)
At the Federal level, USDA has two resources: MyPlate.gov seems the more general of the two, while Nutrition.gov seems more focused on healthy eating (and has a smaller selection). And the NIH also has a heart-healthy recipes site.
Best part: At least some of these don't pad the word count with pages of blah-blah-blah before the actual recipe!
That's just what I could find with some quick web-searching; feel free to drop a link in the comments if your state (or other government if not in the US) Department of Agriculture (or equivalent) has recipes and/or cookbooks available.
