Make Chimichurri Sauce: In a bowl, combine the chopped parsley, chopped oregano, minced garlic, red wine vinegar, and red pepper flakes. Slowly drizzle in the olive oil while whisking continuously to emulsify the sauce. Season with salt and pepper to taste. Set aside to allow the flavors to meld.

Place the chorizo sausages on the preheated grill or in a 400°F (204°C) oven. Cook the sausages to an internal temperature of 160°F (71°C), turning occasionally, until cooked through and nicely charred.

Warm the rolls.

Place a grilled chorizo sausage in each toasted roll.

Drizzle a generous amount of chimichurri sauce over the grilled chorizo sausages.

Serve the choripan alongside pita chips and hummus with coconut water.
