One of my favorite things to do in the backcountry is to try out different recopies I’ve read about online, or watched a video about. NOLS puts together a recipe to cook Quiche Moraine out in the wilderness.
Of course for me, weight is always a factor. Someone on an extended trip into the backcountry will not be able to carry large amounts of fresh food, due to the extra weight from high water content, and will have to rely heavily on food with a low water content, such dried meats and vegetables, packaged dehydrated camping foods, and starches such as ramen, polenta, and dried potato flakes. Wilderness experts in both categories sometimes make use of locally available wild foods as well, particularly wild vegetables and fruit but also occasionally fresh fish and wild game; however, it is not unusual for camping food, especially backcountry food, to be partially or totally vegetarian. However, I think this is doable considering the pot you may have to use to make it.
