Mealworms will help up the protein a bit but they are also high in fat so maybe give a small piece of plain cooked chicken once or twice a week for some low fat protein.
Millet is a good addition but she could probably do with a little more variety really & pellet food doesn't allow them to forage naturally although you could still hide some food around the cage rather than put it all in a bowl.
I don't know where you are but in the US Higgins Sunburst, although still low in protein is quite a good mix that can be used in combination with pellets for more variety.
