These days there are lots of vegetarian options for freeze dried meal in a bag
For example
Can't get any easier....boil water, add to bag, wait 15 minutes, enjoy!
If you haven't used them before take note that the 2 serving versions are really only good for a single person, if you do split them between two people then you probably want some supplement with something like wraps of one sort or another. Some brands are now producing single serving versions which are usually a little bit more than half of the traditional 2 serving versions.
My favourite brands are Backpacker Pantry, Alpine Aire & Mountain House. Happy Yak is a Canadian brand that are very good, kind of pricey and maybe not easily available in the USA.
