Damn, so many I could list. I am a
big fan of savory snacks, chips being no exception.
Favorite of all-time would have to be the Sabritas brand Crujitos Queso & Chile, yes, they are a "puffed corn twist," but whatever:
But, seeing as how I can only seem to find Crujitos in Mexico, my favorite chip that I can find domestically has got to be the Doritos Dinamita line, also made by Sabritas; both the Chile Limon or the Nacho Picoso are fantastic:
