If you're still telling your kids to not eat potato chips, or its your guilty pleasure, it's probably because you didn't know you could make them in your microwave without a smidgen of grease. For real. I could tell you more, but I suspect you're already in the kitchen trying this out.
One Russet potato sliced paper thin
Cut a sheet of parchment paper to fit a plate. Lay discs of potato on top in a flat layer, none touching. Sprinkle layer with salt, if desired. Cover with another sheet of parchment paper. Microwave for 5-6 minutes. Discs will have become lightly browned potato chips.
