For the meatballs, combine all the ingredients and mix well.
Combine all the sauce ingredients and pour into a deep roasting dish/casserole dish.
Form medium sized meatballs and place into the roasting dish.
Place the dish in the oven and bake for 20-25 minutes until the sauce has reduced slightly and the meatballs are cooked.
To make the polenta, bring the stock and milk to a simmer and whisk in the polenta. Continue whisking until the polenta has started thickening then turn down the heat and allow the polenta to gently cook for 10-15 minutes.
Add the butter, cream and season with salt.
Serve the polenta with the meatballs and sauce topped with grated Pecorino and parsley.
