The places around here stock plenty of these options, even the membership warehouse has jumped on the trend.
While heading out from the wholesale club the other evening I caught part of a conversation where someone mentioned grabbing Doritos protein chips. I didn't turn around to check since I was already leaving. I've searched the usual spots near me with no luck and figured the person probably just meant the Quest nacho style ones. I had stopped looking until this morning when I spotted a display at the big box store. The fiber count could be higher and I haven't tried the flavor yet, but here they are. I often recreate a loaded nacho dish using similar chips, sometimes the real Doritos but in smaller portions. If these deliver on taste the added protein would make them a solid swap.
