Just offer salad, and feed dusted crickets x3 a day.
Offer salad and leave in for 2-3 days between changes, as I said before Bilbo never eats the same day I put in even if it's in the morning.
I have heard about feeding bearded dragons 3-4 times a week crickets when an adult, I think this is bull, they would eat everyday in the wild.
So I fed him
0-9 months old x3 feeds a day
9-12 months old x2 feeds a day
12+ months old x1 feed a day
Unless some days I am unable to feed him because I'm out all day, this is very rare, I will feed him x2 feeds the day before and make sure he has pleantly of salad. He has crickets and roaches to mix it up and wax worms as a treat once or twice a week (mainly my 4 year old son gives him the worms as he loves to do it).
He eats, kale, spring greens, bok choy, red pepper, romain lettuce (not often as I dont really buy it) I mix this up too so he does not have to much of the same stuff every day. He does not eat strawberries or squash some owners find they love these though? All beardies are different and so it's just finding what yours likes. I think Bilbo was about 5 months old maybe 6 when he stated to pick at his salad bowl.
Good luck hope all is well
