First, start the grill on medium-high heat and lightly oil the grates.
Add the chorizo sausages and let cook, turning occasionally. Meanwhile, prepare the quick chimichurri sauce.
Place all of the ingredients in a bowl and mix until well combined. You can make the chimi a couple of hours in advance to develop the flavors but, let's keep in mind we are doing a quick sauce here.
Remove the sausages from the grill and cut them lengthways. Cook, cut side down, for 2-3 minutes or until slightly charred.
Add the bread on the grill to get that crispness we are looking for.
While the sausages and hoagies are grilling, make your topping mixture by combining the tomatoes, red onion, olive oil and seasoning.
Cut rolls lengthways and add the charred chorizo sausages in the rolls.
Top with the quick chimichurri and tomato mixture.
Enjoy.
