My favorite are sour cream n onion but Lay's messed with the recipe and they're somehow even greasier than they were before so I don't get them anymore. I like Hickory BBQ and Ruffles with onion dip. But my favorite "chip" are pita chips.
It's hard to pick just one, but I do like BBQ. We make our own chips at work and the ranch kind are so good. They aren't like Doritos ranch, it's a much milder ranch flavor, but just right for the potato chip.
Cucumber potato chips? Now I have heard of everything!
Oh yes, blueberry flavoured, Ice Tea flavoured... you name it... they've got it. It's hilarious to see them!!!! And they put vinegar in everything, and oodles of salt... but no one likes salt n' vinegar.
