Choose a large, blonde onion. Chop it roughly and start gently roasting it in a pan, with 2 tablespoons of EVO oil.
After 10-15 minutes, the onion should change color and become slightly transparent. Time to add the pork ribs and roast each side of them. The heat now is less gentle, but not too much (pay attention not to burn the onion).
After 15 minutes, the roasting should be completed. This is important since it will keep the meat juices inside during the long cooking phase.
While the meat is roasting, wash and cut the savoy cabbage.
Time for the King ingredient of this dish, the savoy cabbage! Add it to the pan and pour about 1 glass of vegetable broth. Cover with the lid and cook at low heat for about 30 minutes.
After this time, add the tomato sauce, salt (optional, I prefer not to) and black pepper (optional, I do). Gently mix, add some more vegetable broth if you think it is too dry, and cover with the lid again. Gently cook it for about 2 hours.
It will be ready when the meat effortless separates from the bone. Your dish is ready to be enjoyed with some good homemade bread!
