Place mince, mixed herbs, zucchini and carrot in a bowl and mix well to combine. Roll into 40 small balls. Heat a non-stick frying pan. Add meatballs and cook until browned.
Add tomato sauce to the meatballs, reduce the heat to low and simmer for 15 minutes. Check seasoning and adjust if needed.
Using a bread knife carefully make a cut lengthways down the centre of the bread rolls. Be careful not to cut all the way through.
Place four meatballs into the centre split and sprinkle with grated cheese ready to serve.
