I guess I wonder why? Isn't a balanced varied diet like in nature better?
Either way why not try Rep Cal Bearded Dragon pellets(my dragons love them) and greens mixed together? Then I guess you could eliminate the crickets. It's better than just greens alone I would imagine.
If dealing with live Crickets is the problem and mind you, I hate LIVE crickets too, may I suggest switching too Zoo Med's Can O Crickets? I've had great results. I use both regular and mini crickets and the dragons gobble them up. They're moist and the exoskeletons are softer because they're cooked in the can. I would dust them when using them though.
