Well personally I would not give the "extras" on the plate with the main meal .... They would get it after they finished all the main part then I would serve the "extras" fruit yoghurt and such afterwards then when she sees the other children getting the good stuff maybe she will eat but if not oh well too bad ..... So for instance if Shepards pie was on the menu today that's all they would get on the plate and when finished they would get dessert (fruit yoghurt ect) ...... That would fix her wagon !
