List of additional seeds to add to Roborovski mix?

[racinghamster]

I`m basically asking if anyone has some other suggestions to what I might add to my Roborovskis already dry hamster mix (Harry Hamster). They have dried mealworms mixed into this and I also add a sprinkle of Kallo organic puffed rice cereal (health food shops like Holland & Barrett) or supermarket organic section. I also add a small amount of porridge oats.

Now apart from pumpkin seeds and a sprinkle of foreign finch seed and budgie millet, is there anything else that robos like to nibble on? I like to think I can give them a nice variety without giving anything too fatty, or anything they really should or should`nt have. Any suggestions will be great.

I`ve tried doing some research on roborovski diets in the wild, but can`t seem to find anything conclusive so far.
