Since Riley is a picky eater and will only eat crickets, small supers, and things that are moving, I had an Idea of getting him to eat greens! (Don't judge me, this worked with Riley and I don't know if it'll work with yours -. -")
1) Attach a long green leaf to a string
2) Put it in your beardies cage
3) Move it around as a real worm would do
4) Yay!
Remember to post ways that you get your beardie to eat his/her greens and I forgot to tell you, don't do this too much or else they will start to figure out.
