My Chi is a picky eater. What do you feed your Chi?

One of our chi's have food allergies. She is allergic to rice and wheat. So we buy beef and cook it with carrots and some chicken broth. We put it in the fridge and feed her that. She likes Liver and Lamb but it is too expensive. It is $5 for 2lbs of beef and some carrots so it isn't that expensive to do and she loves it.
