Should a tortoise diet include more than just vegetables

[JoesMum]

is this common mallow? it seems like it but i would like to double check because i have a ton of it in my backyard

Can you photograph the growing plant please? It's always hard to judge from one leaf.

I don't know what it is but I'm sure it isn't a mallow.

Yes, a full picture would be great. Where do you live; that may help with identification.
