One of my favorites from Sarah's website is the chicken curry cranberry couscous (I may have the order of the name wrong but those are the main ingredients). Aside form the chicken pouch, I had everything else I needed in the house. No dehydrating and all simple, readily available ingredients.
Another staple for me is a quick-cooking noodle (or substitue rice or couscous), a tuna packet, some pistachio pieces, some grated pamersean cheese and a packet of the pesto powder mix (found in the dry powdered suace area of the grocery store). I throw all the dry ingredients in the baggie together at home. In camp, pour in the needed water for the couscous, maybe a little extra to get the pesto sauce runny, some olive oil, then add the tuna/chicken and boom! Ready to eat.
