Try parsley in a food ball that hangs from the top of the cage. The act of pulling pieces out might stir her interest.

I have a 5 month old African Grey.I give her fruit and vegetables everyday.She takes it with her beak,bites it and then flings it away.No matter what fruit or veg I give her,she always does this.She loves rice though and never wants to stop eating it.She also really enjoys her seeds and nuts.What should I do to get her to eat fruit?
