Meanwhile, in a large skillet, soften the onions in the oil. Season with salt and pepper. Add the sausage meat and cook, breaking the meat up with a wooden spoon, until golden. Add the garlic and cook for 1 minute. Add the bread and wine. Cook, while stirring, until the bread has absorbed all the liquid. Off the heat, stir in the Parmesan and parsley. Adjust the seasoning.
