Honestly, I don't think I'll ever find plain potato chips disgusting, or entirely unappealing/unappetizing. I love a good potato chip.
Other questionable edibles I have a much easier time saying "that's not food!" to but I have a soft spot for chips/crisps. Plain only though, I was never a fan of bbq or garlic and onion, etc etc. I also can't stand stuff like Doritos or anything where the flavor is so strong. Obviously, I don't think they're anything to be had constantly, but at parties and such I definitely like to munch on these and don't really feel much guilt about it.
I'm going to go on a Twinkie Diet but with potato chips after whole30. I'm going to prove to you fools once and for all that calories in = calories out and it can be delicious and salty at the same time. Paleo be damned! bring on the crisps. Thanks Steve for showing me the light.
