Good start, but too many folks on SNAP not only have limited funds available for feeding themselves, they also tend to have very little time to cook (the two-hour bus ride to work and childcare doesn’t leave a lot of spare time), and quite often don’t have a full kitchen (e.g. a hotplate and no fridge).
A quick-and-dirty short course on which fast-prep ingredients will give you the best nutrition value might be a good companion book, for those who aren’t in a position to benefit from a cookbook with time-intensive recipes that assume a refrigerator, a stove, and a nearby grocery store.
