In Italy, salsiccia is a fresh pork sausage. Salsiccia is usually roasted in a barbecue (prick the skin with a fork, and watch out for the grease flare-ups), and it can be used for making risotto.
Normally it does not include garlic. Salsiccia is a fairly simple affair, flavored with salt and whole pepper grains.
Many butcher shops make their own salsiccia, which is always consumed fresh. Do not confuse with salame or salamino.
