I have had 2 jaw surgeries resulting in about 12 weeks of no chewing. My neighbor made me one using milk, frozen fruit and a little bit of vanilla coffee creamer I adjusted the recipe this way.
1 envelope of Instant breakfast (extra protein and calcium)
6 oz skim milk
frozen fruit to taste
blend in blender and enjoy.
Favorite flavors were Chocolate instant breakfast with frozen sweet (bing) cherries and an extra squirt of chocolate
The vanilla was good with any variety of fruit. suually strawberry mango, or what ever was in the freezer.
Most people include bananas, but I don't care for them, no matter how good they are supposed to be for me.
Good luck
Susan
