Mre's have pros and cons. Based on the info I have for your situation I'd say get a few. The biggest advantage to them is that they require no water to cook. You can eat them without activating the heater. They have bulky packaging and honestly aren't very tasty, some are far worse than others. I'd suggest just buying some components if you want to try them out. Some are instant heartburn for me.

The drink powders and desserts are better off being replaced by stuff you can get locally.

the patriot supply tub o food is mostly just pancake mixes and soup mixes, instant potatos, and instant rice. Which you could get cheaper at your local store.

If you were to write a check for a survival stash of food mountain house is superior tasting.

If space is limited and you just want calories to stash without worrying about cooking lifeboat rations would be the way to go. They taste like a very bland sugar cookie or a slightly sweet biscuit.

Otherwise the go to is simply taking the meals you normally make and stacking them deep, allowing you to rotate thru the stash far before they expire with a 60-90 day supply you should be able to rotate that in a year.
