Rhubarb Protein Smoothie

I went to make my fruit/protein smoothie last night and we were out of fruit!  This meant I had to improvise, luckily I had some Rhubarb Sauce around. Rhubarb Sauce Approx 3 pounds Rhubarb, Chopped 1 packet Stawberry Sugar Free Jello Splenda (1 cup approx) Put the Rhubarb in a pot with a little (1/4 cup) water and cook it until mushy.  Add jello and Splenda and let cool.  Makes about 1 quart of sauce.  Other than the one Jello packet, I made mine totally without measurements and all was done "to taste" So, now I have sauce but no other fruit and need a protein supplement.  So I put the following in a blender: Rhubarb Smoothie 3/4 cup Rhubarb Sauce 1 scoop GNC Vanilla 1/4 cup fat free yogurt 3/4 cup Light Soy Milk (just me, use any milk really) 1 cup crushed ice It was really good, a nice creamy consistency with a little tang from the Rhubarb.
