We recommend you try a bag of Popchips (or as they type it, popchips). These are low-in-fat potato crisps. They call them chips, which suggests someone slices a potato and fries the slices. I think they're really crisps, which means that someone turns potatoes into potato flour and mixes in other ingredients and then stamps out little chip shapes and cooks 'em. But even though they may try to make their product look like something it isn't, the bag I sampled the other day was pretty good.
They don't fry them like regular potato chips. They don't bake them like Baked Lays. They say they "pop" them like popcorn. I have no idea what that means but it does make them quite crunchy and tasty without a lot of fat. You get about the same calorie count as Baked Lays but I like them even better. (One drawback: They're somewhat more expensive.)
I do not own stock in the company and I do not profit in any way if you buy them. I'm just telling you about something that I tried and liked.
