I knew someone who would eat a tomato for dinner with a few slices of carrots. Nothing baked, just a plain uncut tomato and slices of carrots.
I'm talking a functionnal human being, knowing the concept of cooking and the ability to walk to their kitchen with such a "dish" as they would call it. Not vegetarian either. They did like meat and whatnot. Saddest "meal" I've ever had the horror to laid my eyes upon.
