I'm too paranoid that the food would spoil. Do NOT want food intoxication in the back country! We still have Mountain House, but also use Idahoan instant potatoes-the loaded up variety-usually <$1.00. Also the foil pouch tuna, salmon-even Spam-but the empty pouches need to be carried back out. There are lots of little microwave type noodle meals available-Kraft mac and cheese-put it in a zip loc freezer bag, add water, let sit. The noodles get soft and the bag doesn't melt with boiling water. I experimented at home a little first. Remember that food tastes way better when you've been hiking your behind off, so it may not be a culinary delight at home, but hunger improves flavor.
I buy dry soup mixes and will add canned chicken or tuna to them when I cook them up to get more protein. There are usually some good dehydrated potato soups. I'll also get Yakisoba which is basically Ramen noodles with better flavor, comes in a container that all you have to do is add boiling water, add canned chicken. Easy and cheap!!
