Preheat the oven to 350 degrees F.
Combine all ingredients, except casings, in a large bowl. Put the meat mixture through a grinder and grind according to manufacturer's instructions. Tie a knot in 1 end of a casing and begin filling the casings with the meat mixture, then tie off the other end of the casing once all the meat has been used. Twist the casing into 6 sausage links.
Bake sausage for at least 15 minutes. Meanwhile, preheat a grill.
Remove sausage links from oven and place on grill. Grill until crispy and golden brown. Spice up your favorite pasta recipe by adding sausage slices or enjoy your sausage the old-fashioned way, on a bun topped with your favorite condiments.
