Preheat oven to 180°C/350°F. Line a baking tray with aluminum foil.
Put zucchini, carrot and onion in a food processor and process until very fine.
Transfer vegetables to a big mixing bowl. Add pork/veal mix, salt and white pepper, and mix until combined.
Take 1 spoonful of mixture and roll into a ball (around the size of a golf ball) using your hands. Transfer to lined baking tray.
Repeat until all the mixture is used up.
Bake meatballs for 40 minutes or until cooked through.
While the meatballs are baking, make your glaze by combining all ingredients for the glaze in a microwave-safe bowl. Microwave for 2-3 minutes in 30 second intervals, stirring every pause, until the mixture thickens slightly.
Remove meatballs from oven. Let cool slightly and brush all of them with the Sriracha glaze.
Serve immediately with steamed rice or vegetables. Enjoy!
