Hi there. Since you’re working with an adult you’ll want her diet to be heavy on greens and veggies and lighter on protein (80% greens and 20% protein at this stage). Dubia roaches, BSFL, silkworms, hornworms, and gutloaded crickets are fed to my adults regularly, while their salads consist of beardie friendly greens like collard greens, dandelion greens, endive, mustard, and turnip greens. I usually have 2-3 different greens in their daily salad as well as a good staple veggie like butternut squash. My dragons have salad available at all times during the day. I’ve included a link below to a food chart beloved by members of this site. It not only lists the nutrition content for the items, but how often they should be fed (daily, occasionally, etc.). I give my guys a fruit treat once a week, as fruit shouldn’t be given on a daily basis. But take a look at the chart and hopefully you’ll find it useful when it comes to designing a nutritious daily salad.
