Food is an art; this is true in the mountains too. Over the years, I have learned what works for me. Meals are a careful balance of the following attributes: ease of cooking, lightweight, hearty, easy to digest, and savory.
Here are my tried and tested favorites. Goat milk powder, homemade vacuum packed huevos rancheros (made of hummus powder, instant potatoes, instant refried black beans, powdered eggs, and spices), grapeseed oil, pumpkin seeds, instant lentil and split pea soup, Simply Native Food's Wild Rice Hot Cereal, thick cut double smoked bacon, homemade beef jerky, mac & cheese, and homemade energy bars.
These delights keep us well fueled and climbing hard.
