A health-food company called Terra Chips has a whole line of delicous potato-chip style foods that make your mouth water and are much healthier for your body than the typical potato chips out there. 
You can mostly find them in health-food stores, which of course means they’re a bit expensive ($4.50 a bag at the local Whole Foods). But I don’t mind considering they’re a healthy and tasty alternative to Lays chips. I just tried a bag of their Sweets & Beets ( —> ) the other day and I was pleasantly surprised at the goodness in my mouth. Hope you get to enjoy them too.
