Hey there,
I don’t have much to add to what you already eat, but I did want to mention vegan jerky if you don’t mind the refined nature of it. I’m not vegan, but tend to get nauseous easily on hikes when I eat and a vegan friend helped me out with that tip. I tend to eat mainly trail mix and vegan jerky. Treat foods if I can keep from destroying them are crisped peas and fresh fruit.
