Steps
- Heat a grill to medium. Grill 4 fresh Argentine-style chorizo sausages, turning occasionally, for 30-35 minutes, until deeply browned and the centers reach 160°F / 71°C.
- Meanwhile, mix ¼ cup of finely chopped white onion, ¼ cup of finely chopped parsley leaves, and 1 small finely grated garlic clove.
- Stir in ¼ cup plus 3 tablespoons of extra-virgin olive oil, 3 tablespoons of red wine vinegar, ½ teaspoon of kosher salt, and ¼ teaspoon of ground black pepper. Rest for at least 15 minutes.
- Split 4 crusty hero rolls, each about 6in / 15cm long, almost all the way through. Add a sausage to each and spoon over the chimichurri.
