Preheat your grill to medium-high heat.
Place the chorizo sausages on the grill.
Cook the sausages for about 10-12 minutes, turning occasionally, until they are browned and cooked through.
While the sausages are grilling, place the sliced sandwich rolls or baguettes on the grill, cut side down.
Toast the rolls for about 1-2 minutes until they are lightly browned and crispy.
Place a grilled chorizo sausage in each toasted roll.
Spoon chimichurri sauce generously over the sausage.
Enjoy your meal!
