Using a griddle pan or a skillet, cook the sausage per package instructions. Set aside.
4 Italian sausage links
Split the ciabatta rolls in half lengthwise and drizzle with olive oil. Lightly toast them on the same pan that you cook the sausage in or a grill.
1 tablespoon olive oil, 4 Ciabatta rolls
In a bowl toss the arugula, olive oil, lemon juice, salt and pepper.
2 cups arugula, ½ tablespoon olive oil, ½ tablespoon lemon juice, ½ teaspoon salt, pepper to taste
Place the arugula mix in the bottom half of the ciabatta roll, place the sausage (I like to split it in half lengthwise) and top with 1 tablespoon of chimichurri and pickled onions. Place the other half roll on top.
4 tablespoons chiminichurri, pickled onions
Serve and enjoy.
