Preheat oven to 175 degrees.
Pop eggplant, zucchini and cauliflower onto a baking tray, drizzle with olive oil and using your hands, mix olive oil through. (Note: you could bake any of your child's favourite vegetables for this). Sprinkle with salt and pepper and pop in the oven.
After 20 minutes remove from oven and pop meatballs on the same tray and put back in the oven for another 20 minutes, or until meatballs are cooked. Remove from the oven and chop up the meatballs.
While the vegetable/meatball tray is in the oven, heat olive oil in a small pan on the stove and add the onion. Saute for around 5 minutes.
Add the rice and stir it through the onion, add 2 cups of water and bring to the boil. Lower heat to a very low simmer and cook rice and onion with lid on for 15 minutes. Once rice is cooked, turn off the heat, and mix through the baked vegetables and meatballs.
While the rice is cooking throw together the cabbage, cabbage, carrot and mint to form a salad
