Crunchy alternative to chips?

Chips to me are like smoking, but I had never smoked. I only know it's good to remove stress, but the only thing I want is the crunch. For people I found online I found they need a lot of things about a chip, I only need crunchyness, doesn't even have to be a chip, sometimes cookies are a good alternative

Any options?

edit: Something I didn't consider is that I would hate for it to leave a bad smell on your breath. It can't have garlic
