I'm vegetarian and my Savannah Monitor used to try and eat me all the time.
The obvious answer is bearded dragons, but they might seema bit "basic" to you. In truth, I find my bearded dragon more difficult to keep properly than my Ackie - partly because she's a rescue and partly because of the amount of ridiculously poor care information that there is for them. She's really flourished since I've had her, and I've found her a hugely rewarding animal to keep. They eat a lot of insects when they're young but do shift to a msotly vegetable/fruit based diet once they get a bit older.
I do love chucks and uros though. I've never owned either so I can't comment on how easy they are to keep. Chuckwallas (Sauromalus) are Igauanids though, and as closely related to "true" iguanas as the desert iguana (which are from the Dipsosaurus genus, not the iganua genus, although they are still iguanids). Pretty sure Uros are agamids. This is, of course, largely irrelevant, but I find it interesting.
