I process the fruits, such as cantaloupe, with the leafy green veggies until it becomes finely chopped. This way your bearded can't pick out his favorite fruits... Gradually, over time decrease the amount of fruits so he is just almost eating the greens all by itself. You can add red bell pepper to make the salad look appetizing to encourage him to eat. Make the salad as brightly color as you can. Try using things slike winter squash, carrots and red bell peppers to give it nice colors.
