I cook more with feeling than recipe and I as I hike for multi days I try to vary the meals to avoid getting bored. My typical bag includes multiples zip bag with ingredients and I pick a few to make a meal:

- semolina of wheat, whole wheat, rye, lentils and chickpeas

- flakes-instant smashed potatoes / adzuki beans. Instant quinoa packed with prots but miss carbs.

- sesame seeds, sunflower seeds, pumpkin seeds

- dried seasoning algae, yeast, zaatar or thyme. Curry powder or other spice mix.

One of my favorite mix is 1/3 lentil semolina, 2/3 wheat semolina, sesame seeds and yeast. Mix together, add water and cover for a few minutes.

Edit: last year I used a food dehydrator to pack some sauces and cooked vegetables. Works great for the ones in think slices.
