Hello,
I am having the exact same problem with my beardies too.
I have gotten them to eat their greens by stopping all insect feeding’s for two weeks. Eventually they will get hungry enough to eat their greens, Also, Variety is key to making them eat. She does look fine to me, But are you sure she isn't carrying infertile eggs?
Could you post some pics of her setup? What are her cage temps(Basking spot, cool end, warm end,)? What size tank do you have? What do you feed her? How long is she? How much does she weigh? She does look a bit on the dehydrated side, so you should give her more water.
