My wife does the same kind of thing, except she wrote a whole web app that I host on my homelab server (we're both rails devs). The app keeps track of upcoming meals on a calendar, number of leftover servings in the freezer, ingredients needed for upcoming meals, etc.
What an organized person. I just pull stuff out of the fridge and randomly cook whatever I can with it and if there's no good option I go to the store to buy some random things to resupply the fridge.
