Uromastyx. They're strictly herbivores I believe, as well as iguanas (though I wouldn't recommend an iguana without extensive research)
Blue tongue skinks would do fine with the Repashy omnivore mix (Savory Stew? Don't remember) and mixed greens. As far as I can tell they'll eat about anything. Some people keep them on a diet of wet dog food with add ins and it's worked for years, but with a omnivore reptile diet available it seems like it would be better suited.
And there's the classic Cresteds, but when you say lizard I'm thinking you mean not a gecko. I could be wrong though
