46 oz. can unsweetened pineapple juice
1 can crushed pineapple (vacuum packed)
3 very ripe bananas
1 tsp. or less lemon juice
12 oz. can diet 7-Up
12 oz. frozen unsweetened concentrate orange juice

Blend bananas well in processor or blender. Add pineapple and blend. Add remaining ingredients (except 7-Up). Blend and freeze in individual serving containers. (2 lb. size butter bowls makes 4 servings). Set out 15-30 minutes prior to serving. Then pour some of the 7-Up over tops. Will make a mush-ice consistency.
