Chop cranberries and orange after washing first. The orange can be chopped with the peel on and seads in -- really! Cover the chopped fruit with sugar and let set overnight.
Drain and save the juice from the cranberry/orange mixture. Add enough water to the juice to make two cups of liquid (1 hot to dissolve the gelatin and 1 cold). Mix the two pkgs of Jello with the the two cups of liquid. Let partially set.
Dump in everything -- cranberries, orange, celery, and nuts. Stir well. Chill (that's the salad -- not you).
Serve with the meal. Then hide the rest for you. =).
