A small cup of rolled oats and milk or water. Doesn't taste like much (this is a feature here), doesn't induce sickness easily, takes no time to prepare, is very mobile (can be carried around while getting dressed), gives sufficient energy and is easy to eat without appetite. My go-to solution when I need to have food but really don't want to. Plus it stores really well if you use water, so no need to get fresh ingredients.
