Hi,
Since we have a diabetic in the family I'm always looking at ways to change the recipe to suit us.
I would use sugar free jello (at least strawberry - I'm not sure if they have sf berry blue). Low to no-fat milk, sf instant vanilla pudding and "whipped topping" FREE!
I have had all the changes I am suggesting at different times and they taste very good. This should be delightful even with my changes!
Thanks for the recipe.
