Judy's right, feed it raw. Cooking robs nutrients, same as with commercial dog food--when it is heated, vitamins, enzymes and protiens are less.
I was super worried about feeding chicken, and vowed to stick with red meats....but, what the heck, we have chickens so why not? The first time is the hardest, then you get over it.
Certainly try to feed whatever foods you decide raw. For fruits, papaya is very good and my dogs enjoy it. I sneak some of this in with their meats, which is devored. Pumpkin seeds are okay, they contain a high amount of Vit. A (I feed them to my birds) but they do contain a high amount of Phos (332.83mg).
A good way to look up the nutrients in foods is through the NAT. Here's their site
