Into a large bowl add the veal and beef mince and break it up with a wooden spoon. Tumble in the crushed garlic, dried breadcrumbs, Parmigiano and egg. Stir well with a wooden spoon to incorporate.
Sprinkle in the chilli flakes, dried oregano and parsley .
Add a good sprinkle of salt and pepper and mix really well. I do prefer to use my hands to mix the mixture well.
Onto a clean board lay a sheet of parchment paper, this will ensure the polpettone mixture will not stick and will aid in rolling. Spoon out the meat mixture onto the parchement. Using your hands press the veal out to a rectangle, approx 3cm deep 40 x 20cm , a large rectangle.
Take the sheets of speck and lay them across the polpettone.
Top with basil leaves and then lay the boiled eggs across the centre of the polpettone rectangle.
Gently roll the polpettone (sinilar to a swissroll) until rolled and sealed. Seal and fold in the sides until you have one large looking sausage.
Lay the polpettone into a large oven proof dish and add 150ml vermouth. Seal and cover with foil for 50 minutes. Then remove the foil and finish cooking.
Slice and serve with whipped polenta and cavolo nero steeped in garlic, chilli and passatta.
