Recipe suggester based on what's in your fridge

Every Sunday I stare at a half-empty fridge and order delivery anyway because I can't figure out what to make. I want an app where I take a quick photo of my fridge and pantry, and it tells me 5 recipes I could make tonight with those ingredients — sorted by how much I'd actually need to buy. It should know my dietary preferences (I'm vegetarian) and ideally remember what I've made before so it doesn't keep suggesting the same pasta.
