I have a 5 month old beardie that loves his phoenix worms (about 60 a day) but won't touch his greens at all! I know that when they're young they prefer their protein over their greens but I was wondering at around what age should the transition to a more vegie diet be?
It varies between individuals. It has to do with when they approach full size and their growth (and therefore appetite/metabolism) slows down. It's usually a gradual transition between about 12-18 months but that's not set in stone. Just keep offering salads and eventually they tend to start digging in more while not eating so many bugs.
