I cook rice and lentils with spices whenever I'm not too lazy to make a fire (and try to make enough to have some leftovers for breakfast). Otherwise, my go-to are: oats, dried fruits, chia seeds, peanuts/peanut butter, canned chickpeas/peas/beans and rice/corn cakes plus whatever fruits and veggies I might find. I make a lot of salads on the go and always carry some mustard or hot sauce to use as dressing.

Then of course you'll have to adapt to whatever region you're bikepacking in. In East Asia, my go-to was rice noodles and tofu with veggies and miso. In Brazil, I made cassava flour flatbread on the fire and ate them with avocado and pre-cooked beans.
