Can I feed this to my hamster?

So I had some leftover fried fish and a piece of chicken cooked in curry today. I washed the chicken first before mashing it up with the fish, together with hamster food (powdered this), sugar, salt, cooked rice and boiled spinach. I then rolled the mixture (like cookie dough) into small balls and fed it to my hamster. He seems to like it. But is this good for him in the long run? I did this because he doesn't seem to be eating his commercial hamster food anymore. I think I've spoilt him by giving him meal worms every single day.
