If I can’t vary the recipe (it needs to be the exact same every time), I’d probably live off something inoffensive and bland. Like polenta with fried eggs.
If there’s some room for variation however it got to be stew. It’s still a stew if I sub potatoes with taro. It’s still a stew if I sub the beef with chicken or fish. It’s still a stew if I change the seasoning. You get the idea, right?
