Yogurt!

In my recipe I blend yogurt with water to get a milk texture.

Soy bean milk is another great option (if you do not suffer from the thyroid - stay away from it if you do - if you are not sure, try it and you will soon find out if you do have thyroid issues).
The vanilla soy bean milk tastes much better (some brands have sugar, then buy the plain type and add vanilla yourself).
