Ann, I did a search on Altavista - "Protein Shake" and found this link. I've never tried it but you might be able to substitute the milk (if necessary) with Soy Milk or Rice Milk.

Choco-nana Peanut Butter Protein Shake

You can also do a search at Google with better results.

Good Luck!
Hope you find your recipe!
Grumpy!

I've tried out this recipe my niece shared with me and it's delicious.

1 cup of vanilla soy milk
1 frozen banana
2 dates, chopped and pitted
1 or 2 tablespoons of any kind of nut butter. (I've
tried using peanut butter and it tastes like a reeces blizzard at dairy queen. And soy butter tastes the same as
peanut, but offers less fat, more protein).

Blend all in a blender and enjoy!

These are so good and have a lot of nutrition, and even more if you use enriched soy milk.
