Take small snack rye or pumpernickel bread and lay it out on cookie sheet. Slice a big, red onion and put slices on the bread. Spread Miracle Whip on top of the onions and the bread. Sprinkle top with Parmesan cheese. Put in oven and broil until brown. Watch carefully!! Delicious before dinner, or anytime. Enjoy!! Can be done up ahead and refrigerated. Make as many as needed.
