You're going to get all sorts of great advice here.

The nuts and fruit are great dietary supplements, but they don't make a diet by themselves. Nuts, for example, are very high in fat and can cause a lot of health probles if too many are fed. Fruits are great, too, but only when used with lots of veggies, grains, and a good commercial diet.

Commercialized bird diets are now readily available on the pet market. They're commonly referred to as 'pellets' and contain everything that a bird needs nutritionally. Most pelleted diets recommend that they be fed exclusively as the bird's diet, but most bird people feel that fruits, grains, veggies, nuts, and occassional seeds and eggs are great complements to a pelleted diet. The biggest reason is this: how would you like it if your food looked and tasted the same every single day?
It's pure enrichment to add different tastes and textures into the mix.

Not all pellets are created equal. In my opinion, the two best brands on the market are Zupreem and Mazuri... besides Harrison's, which is THE best choice of food to feed, but it's very very expensive, especially for a bird that isn't yours. Mazuri is the choice food of zoos, and we feed it to our parrots at the aviary. I had already started my birds on Zupreem before Mazuri became available, and I like it enough to keep it that way. I use the colored pieces. Some people think that the colored pieces don't mean a thing for the bird, but I think it's more stimulating than eating the same color over and over again, and my birds actually have colors they like better that they eat first and colors that they hate and leave for last.

The pelleted diet should be fed every day as the staple.

In addition, fresh fruits and veggies should be offered every day. Don't get too carried away with them; make sure there is still more pellet than anything else.

Egg or meat products can be offered two or three times a month. Make sure it's thoroughly cooked and contains no sauce or anything like that.

Likewise, seeds can be offered a couple times a month as well. Again, make sure its just a small treat.

Nuts can be offered 2-3 times a week, in moderation (in other words, only one nut at a time, depending on size!)

Grains can be offered 3-4 times a week. Obviously, wheat bread is one of the best grains, but my birds go absolutely nuts for plain pasta as well. Stay away from salted crackers.

A plucking CAG with irritated skin would also benefit from 2-3 showers a week. I haven't worked too closely with CAGs, but from what I hear, most don't enjoy this. Offer him a dish of water to bathe himself first, and if he doesn't seem interested skip right on ahead to misting him. Try not to scare the crap out of him, but make sure he gets wet. It will benefit him in the long run.

Additionally, make sure he has plenty of toys. CAGs have busy minds and need to be kept stimulated.

There will probably be some differing opinions on what to feed and when to feed, but overally you should get a good idea of what to do.
