Good snacks that are low in sodium?

Struggling with sodium limitations lately. I really want to stay on top of that, along with my calories, but my problem right now is that all the things I love to eat for snacks contain a lot of sodium. Any kind of chips, nuts, trail mix, protein snack bars, PB, etc etc etc.

Anyone know of some recipes for low sodium snacks? Or just foods in general that I can munch on that will keep the sodium down. Fruits, veggies--bring me everything you got!

Side note: I'm a vegetarian, so no meat please. :3
