You wont click!!!! xD?

Ok so I have a problem well not necessarily a problem but a thing that bothers me a bit. OK so I have this amazingly cute Albino gerbil named Ice. (Yes I know very original =D ) And the only things she has in her cage (10 gallon tank) is a chewing log for gerbils/hammys, a salt wheel, a wooden hutch and a water bottle. "wheres the food bowl?" you may be asking, well she buries it so I put it at the top of her hutch and she will happily eat up there. :) So heres the thing, I have no clue what to put in her cage to entertain her. I know tp/pt rolls but what else? She did have a puzzle playground from petsmart but she chewed it ad then I read in another question not to let them have plastic. So that had to come out. :( So what I am really asking here is, what can I put in my Gerbils cage? Please attach pics of your Gerbil cage so I can get an idea of what mine should look like. Thanks a million! Oh and another thing, what are some things I can feed my Gerbil? Don't say chocolate because I am not an idiot and I know better. =D Thank you!!!
