Need help on a Mali Uromastyx (lizard)

I am totally out of my realm here, but a young friend asked me today "What else would his lizard like to eat?" He said it likes dandylions, but wanted to know what other plants he could grow for his pet.

This young man is very responsible, very intelligent and I have been gifting flowers to this couple for about two years, what I have shared with them through DG has impressed them, but I cannot get them on DG, it's an "old" deal..well, yeah, I am old, but not all of us are. I know there is someone here who can intelligently answer this question. Any help is very much appreciated.

Thanks, Peg
