My grandpa is in a nursing home, he has cancer among other things.. (high blood pressure, diabetes, high cholesterol..) He really likes shakes, but he can only have sugar-free ones. I'm going to visit him on Saturday and I'd really like to make him a chocolate or vanilla soy shake that's sugar free. I've found some sugar free soymilk, but I don't know about ice cream.. He certainly doesn't need the milk either, so I think soy would be a great option. Anyone have any ideas?
