When mixing your bearded dragon’s food, we recommend using a variety of different types of vegetables. You should mix mustard greens with collard greens, broccoli, alfalfa hay, turnip greens, kale, parsley, watercress, Swiss chard, cabbage, bell peppers, green beans, and dandelion. You can also pair mustard greens with cooked sweet potato, cucumber, sprouts, squash, okra, mushrooms, carrots, asparagus, and corn. Mustard greens also go well with fruits! These are fruits such as apricots, figs (high in calcium), raspberries, dates, and strawberries.
