I will also vote for MREs.

Minimal prep, throw the packet in hot water for a few minutes. No cleanup/dishes to wash, and they really are not bad tasting. You can also eat them cold.

Sounds like you aren't looking for a gourmet meal, you just want some fast/easy palatable nourishment. This is pretty much the definition of MREs.

On Edit, the photo Gogar posed above includes the entree heater, that is even easier and faster than boiling a pot of water. The downside it you can't use it for coffee after your food is hot.
