Preheat oven to 300.
Season the ribs with the house seasoning blend. Heat the oil in a large roasting pan over high heat. Once hot, sear the rib pieces on each side until browned. Do not overcrowd the pan. Work in small batches if necessary. Once browned, set the ribs aside and lower the heat medium-low. Add the onions and garlic and cook, stirring frequently, until softened, about 4-6 minutes. Add the tomato paste and stir constantly for 5 minutes so as not to scorch.
Deglaze the pan with the wine and reduce by half. Add the tomatoes, salt and pepper and continue cooking for 5 more minutes. Cover and place in the oven for 1 hour.
Serve over polenta.
