What vegetable does a bearded dragon eat?

The adult bearded dragons staple diet should be dark, leafy greens, like collard greens. Very young lizards need to have lots and lots of insects, crickets are a good choice for this. You should start introducing vegetables at a young age. The best veggies are collard greens, mustard greens, escarole, endive, turnip tops, dandelion, and raw shredded butternut squash. Mine tend to like Endive and collards the best and they all love the squash.
