If you go to the website: BeautifulDragons.com, you will find a complete food list of all of the foods that your beardie can eat, along with recommendations as to how often they may be fed, and their nutritional value. The list also includes things that they shouldn't be fed, and is an invaluable tool for any beardie owner to have as a reference in planning their diets. This is a printable list that you can keep on hand and refer to at your leisure, and most of us here on the forum have found it to be very helpful!
On a personal level, my three spoiled brats love slices of raw apples, mangos, bite size pieces of cantaloupe, strawberries, raspberries, and small pieces of banana, on occasion. They also go absolutely bonkers for watermelon (but you need to make sure not to give them any seeds, or buy the seedless type). All three of them also love applesauce, and will eat it from a spoon, when its offered. LOL
