Not for nothing my conure likes berries and apples and basically anything I eat but before all that he liked...well likes... those dried banana pieces that come in Sunburst true fruits.
So one day I bought some bananas. He couldn't care less for them. Maybe because I'm not really into bananas as much as grapes, apples, oranges strawberries, peppers etc. So I don't buy bananas anymore, I just get what I like and have to fight him off to get my share.
In short, my advice is the same as Scott's eat some yourself and then try to keep him from your food.
