one other thing, in terms of frugality and "good for the earth" sort of thing- the More with Less cookbook by Doris Janzen Longacre has a lot of frugal recipes with less meat and such. Focus is on forming complete vegetarian proteins, and there were a few recipes in there that could be considered low-carb. A lot I couldn't have due to being based in grains, but I think you'd appreciate the philosophy. ;)
