Mac & Cheese doesn't really fit that bill right? It's carbs, salt and fat. A desert in terms of nutritional value. Barely any vitamins or fibres. Though I do agree with the "anything you can stomach". I'm also ill and a few days ago I barely ate anything. I just wasn't hungry and couldn't really get any food inside. But I did have a huge craving for sweet stuff, so I ate absolutely abysmally but it was better than nothing.
