On the Dr. Oz show today, there was a defatted version of fish and chips that looked disappointing as far as the fish was concerned (steamed naked in microwave). Instead of tartar sauce the chef used all its components except mayo so it was a green relish - that might be promising. But the intriguing idea was the chips. He used very thin mandolin-sliced potatoes. The slices were threaded onto a wooden skewer with close to a half inch between slices. The ends of the skewer were balanced over the ends of a pyrex baking dish which then was nuked for several minutes. I suspect that's asking for a pyrex explosion
but might try this with a different ceramic. If the cook is not married to totally non-fat, the slices could be lightly spritzed with cooking spray or other oil before microwaving. Anyone ever try either method for spuds?
