Yeah, the thing with "unflavored" Protein powders is that they're not actually flavorless, they just don't have ADDED flavor (like chocolate or whatever), so they still taste protein-y, just with nothing to mask it.
It was touted as having no flavor so I thought I could add it to food and mainly Water with nothing else to instantly increase Protein but it was not flavorless enough to use often. I kept reaching for traditional flavored Protein Shakes and at $50 a canister it wasn't worth it IMHO
Isopure, Syntrax, Unjury, and others have unflavored (not to be confused with flavorless -- it has a protein-y taste, just not any added flavor) Protein powders you can mix in with various things to give them a protein boost. I'm not sure how well they work because I haven't tried them myself.
Unjury has chicken Soup flavored protein; Celebrate has chicken soup and Tomato Soup (at least for now -- I was told the Tomato is being discontinued).
Personally, I love the Syntrax Nectar powders the best; you can buy custom sample packs of them at mybariatricpantry.com so you can try individual flavors (up to 10 in a pack, I think) without committing to a whole tub. Some stores also carry single-serve packs, but stock is often limited to just a couple flavors.
