how much food per day for a dwarf?

[Brittttaaannyyy]

I am mixing three foods together for her currently because I bought the wrong kind twice. There isn't anything wrong with any of them, they just aren't a complete diet by themselves. I mainly give her a complete diet, high protein food. I mix in some complete diet pellets and some seeds from generic hamster mix. Once the other two bags are gone I will just be using the high protein complete diet one. I will definitely try to give her some fresh veggies. Thank you all for all the advice!
