Healthy and tasty recipes for on the go?

Hello fellow Redditors!

I'm traveling a lot, and I'm always having some muesli or chocolate bar with me. I'm looking for some recipes to cook and prepare, which feeds me while I'm on the go. And the result should be healthier than all those sugary stuff I'm currently buying.

Do you have some go to recipes for something like that? I got a few muesli bar recipes, but I'm trying to expand my horizont. ;-)

Thank you!
