I am one of her supposed target audience. I have little money, only basic cooking experience (can make stews casseroles full roast, but don't have much imagination) and receive foodbank stuff from time to time.
When my foodbank box arrives and there's something in it that don't know how use, couscous for instance, I turn to Google. I Google "item" plus "easy recipe". I can categorically state that never has one of her recipes come up to assist. Though many, many others do. I actually find BBC the best resource.
I know some cannot afford internet, so Google is not always available, so a book can be useful, though she's already covered that. Though there are many, many better budget cookbooks out there.
The four bedsits on my landing (studio apartments they are called on my agreement) share 1 internet connection between us. The router is just outside my neighbours door (it's her connection) and we all chip in each month. We have found our own way to overcome at least that difficulty. I had better warn next door, JM triangulation skills will lead to her, so she had better watch her back.
