From a diabetic cookbook - made with orange jello, it's sort of like a creamsicle. 32 calories per serving.
3/4 cup boiling water
1 pkg (4 servings) Sugar Free Jello, any flavor
1/2 cup cold water
8 ounces plain fat free yogurt
1 tsp vanilla or other desired extract
Stir boiling water into Jello in large bowl at least 2 minutes until
completely dissolved. Mix cold water and ice cubes to make 1 cup.
Add to Jello, stirring until slightly thickened. Remove any remaining
ice. Stir in yogurt and vanilla. Pour into 5 dessert dishes.
Refrigerate 1 1/2 hours until firm.
