Hello Fresh, at least, has 8 or so available recipes per week. They'll pick 3 for me, but if I choose I can log in to their site and pick for myself.
I tried Hello Fresh and thought it was useful. As a capable cook, it still saved time I'd otherwise spend shopping (30 mins easily if you have a kid in tow) or wondering what to make (on nights I want to cook something new, I will spend 30+ minutes looking at cook books or recipe sites). Someone wanting a less hand-holdy experience could easily ignore the recipes and use it as a mystery box to invent from.
