Moroccan Chicken Casserole

Wife made this and the whole house smelled great when I got home. But I must say it did not ring my bell as much as it did hers. In all fairness it was better the next day.
Funny when something has all the ingredients you love but does not rock the boat.
I think it had to much ginger and that it was a little overpowering so if you are not used to ginger very much I would half it.
