Mix all the ingredients except the casing in a large bowl. The easiest way is to use the hands
Stuff the casing with the mixture, using a sausage stuffing attachment. Let the sausages set in the refrigerator overnight.
Next day over the sausages with cold water, bring to a boil and simmer gently one hour. Or place the sausages in a large roasting pan and roast them in a preheated 350 degree oven for one hour. The sausage is good hot or cold.
