To grill Italian sausage, preheat the grill to medium-high. Place the sausages on the heated grill grate, and grill the sausages for 10 to 15 minutes or until heated through, turning the sausages frequently throughout the cooking process.
Generally speaking, Italian sausage is a type of pork sausage that is seasoned with garlic and fennel or anise. Hot Italian sausage also usually includes chili peppers or red pepper flakes, while sweet Italian sausage is generally made without the peppers or pepper flakes. Grilled Italian sausage is usually served as an appetizer, as the main meat ingredient in Italian sauce recipes or alongside grilled peppers and onions.
