This is pretty cool! I built a prototype of something similar last year: starting with your family's macros and meals, it fetches recipes and a list of ingredients that fit. It's structured as a traditional optimization problem so you can, for example, minimize the length of your shopping list or meal prep time. https://planmyrecipes.com/
This is very cool! Some visual feedback on the website: the vertical padding between the images and text looks a little tight/off, at least on mobile. I think tweaking aspects like that would make it look substantially more “legit”.
