Have you tried feeding her outside?

I don't know too many dogs that resist ground beef, chicken livers, and fried chicken... Putting a little crappy canned food over her kibble helps too. It's kinda weird but sometimes dogs will eat absolute crap and enjoy it. Try sprinkling the crappiest food you can find on her good kibble(beneful works great here for getting a dog to eat). Just use a little so she will get mostly good kibble.
