This is cool I have a similar thought in mind as well as far as having specific meals/ingredients to buy and suggest at random with cost for next grocery run.
Looked at the repo, any screenshots of the UI/interface?
I don't have any on hand, but it's extremely bare bones. Plain HTML, no CSS, no JavaScript. Also I don't have a permanently running server yet, I just boot it up with a sqlite db in Git when i need to use it. Might respond later with screenshots if i remember when its more convenient for me.
