I'd go with Sykk's viral ebook idea (I've done it before, works well) - but include in the ebooks a page that opens up to your site and pulls in the free recipe or note of the day. You could either just make it a link in the book or have it pull right into the book with an SSI type of include (most ebook software does this now, if not, do it with freely found javascript).

If I were doing it, I'd go with "healthy" food - not as in fad diets, but as in not using salt, refined sugar, anything with dyes in it, etc etc.
I used to run a bakery in a big grocery store that only sold natural foods and we baked with molasses, honey, unrefined sugar, no dyes, natural butter (no margarine) etc etc - the money those people would pay for this stuff was UNREAL. Many of them needed it because of food allergies but the rest were just snooty people who wanted to brag about how "pure" and "expensive" their food was.
