In a large saucepan, cook the bacon until the fat is rendered, 4 to 6 minutes. Remove the bacon using a slotted spoon and transfer to paper-lined plate to drain. Add the venison to the hot oil in the pan and cook, stirring occasionally and in batches if necessary, until well seared. Remove from the pan and set aside. Add the onions, bell peppers and garlic and saute over medium-low heat until tender. Stir in the wine and the tomato paste. Bring the mixture to a boil. Stir in the dry spices, chopped tomatoes and the beef stock. Season lightly with salt and pepper. Simmer uncovered for 35 to 45 minutes, or until the sauce is very thick and flavorful. Add the venison to the pot and cook, stirring, until just cooked through and hot, 3 to 4 minutes. Check the seasoning and serve with the grated cheese.
