Good list there, Spicky ... that covers everything.
I suppose some people do offer cabbage. But cabbage is a really heavy tough veggie that is hard to chew let alone digest for a small birds tummy. So why offer it ?
As for breads ... allot of breads contain salts. Salt is bad for any budgie. Some people do offer bread or toast to their birds. But I'm sure they don't offer this very often. Never offer toast that has any margarine or butter on it as this can only harm your bird as its fat & has more salt & chemicals in it a bird should never have.
If you do offer toast/bread it should be a whole wheat bread or a bread with many grains. Never give that soft fake white processed flour bread, as its full of chemicals & salt & allot of sugar.
