Recommendations for bars /protein bars

I am looking for a filling granola bar or a protein bar that you would recommend that doesn’t have a million ingredients and tons of sugar. I do lots of walking most days for my jobs and often just need a quick snack in morning to hold me over till lunch or mid afternoon snack. I have been eating the RX bars but seem to have a lot of sugar and find the barbells way too sweet . Maybe you have some other ideas for an easy healthy on the go snack?

Thanks!
