Some of the backpacking meals are pretty good and easy as cuposoup to fix. They do cost a bit more but provide well balanced meals.
I started out on an 18''cat and now have a Hunter 23 with a little more space and a stove that I don''t have to find a beach to cook on. One meal I like is canned green beans and little potatoes with bits of sausage stirred in. You can also use beef jerky if cold storage is a problem.
There are lots of things in the grocery store that are freeze dried if you look carefully and they are quick fixes.
Try adding jerky thats been soaked a while to your Ramon noods.
Also as I travel, I try to find bars with free munchies at happy hour when I go into town. Jay
