Preheat oven to 200 degrees celsius (fan-forced).
Line 2 baking trays with baking paper and set aside.
Place the zucchini and carrot into the Thermomix bowl. Press Turbo 5-10 times, or until finely grated (you'll need to scrape down the sides of the bowl a couple of times).
Place the grated zucchini and carrot into a sieve and strain out any excess liquid. Place the strained vegetables back into the Thermomix bowl.
Add the strained corn kernels, chicken breast mince, dried breadcrumbs, chicken stock powder and the egg and mix on Reverse Speed 4, 20 seconds, or until completely combined (you'll need to use the spatula to assist with mixing).
Take tablespoon-sized portions of the mixture and form into a nugget shape.
Coat with the panko crumbs and place onto the baking trays.
Spray the chicken and vegetable nuggets with cooking spray.
Bake for 30 minutes or until cooked through.
