Prepare instant mashed potatoes as directed on package, substituting milk for water. Dissolve unflavored protein powder (I like unjury) in milk- add mixture to the mashed potatoes to thin them. For flavor, add a little garlic salt, fresh ground black pepper, and a dash of spicy mustard.

sounds delicious, but I am going to use sweet potatoes instead of white potatoes.

How's the Unjury unflavored? I thought the isopure would work for me, but it just makes every too thick (mixing with soups only) and is starting to upset my stomach!
