my only guess is that maybe it wasn't cooked all the way??? and maybe with the grill there is more fat .. like grease you know?? when you boil the chicken it is kinda bland... no flavour really.. but i imagine if you grill it on the george grill.. there is a bit of juice that it cooks in (even tho most of it drains) i'd suggest just boiling.. but i'm sure she appreciated the change in flavour
