This probably sounds a bit silly, but what about if you got her eating different things by crumbing them? If she is a fish finger and nugget fan, she obviously likes things crumbed - could you make up some home made vege fingers and crumb them? I reckon you could google a recipe Maybe mince some chicken and mix them with grated carrot/zuchinni/any vege really and crumb them? And then gradually increase the vege ratio as she eats them (assuming she does)
