I'd follow your vet's advice. If this is the food that you and your vet have decided to feed, then offer the food, wait 10 minutes, then pick it up until the next meal time. A dog will not starve to death when food is available.
You'll probably have folks tell you to choose a different kibble--there are many out there, and each has a loyal following. I don't know much about kibbles. If this brand is working out for you and you feel that you just have a stubborn pup, then wait her out. That said, perhaps a change of kibble might be just the thing to satisfy both of you---she'd get a kibble she likes better and you won't have to cook any more. With what you'd save on chicken, you could get one of the "better" kibbles. Worth considering. If you try a new one, start with a small bag to see if she likes it.
Good luck. (I don't think she looks too skinny in your photos.)
