Instructions
Make the chimichurri: combine parsley, oregano, garlic, and onion; whisk in red wine vinegar, salt, black pepper, red pepper flakes, and olive oil. Add 1–2 tablespoons water as needed to loosen, then taste and adjust.
Let the chimichurri rest at room temperature for 20–30 minutes while you cook the sausages.
If using salsa criolla, stir together diced onion, bell pepper, tomato, vinegar, olive oil, salt, and pepper; let it sit 15–30 minutes.
Prepare the heat: preheat a grill to medium-high (about 450–500°F / 230–260°C) and oil the grates, or heat a cast-iron skillet over medium heat for 3–4 minutes and add a thin film of oil.
Grill or sear the sausages whole, turning occasionally, until browned and cooked through, about 9–12 minutes (or 10–12 minutes on the stovetop). An instant-read thermometer should read 160°F / 71°C. Rest 2–3 minutes.
Split the rolls (leave a hinge) and toast cut sides on the grill or in the skillet until lightly golden, 1–2 minutes.
Optional: butterfly each cooked sausage by slicing lengthwise almost through and opening like a book.
Assemble: place a sausage in each roll, spoon 1–2 tablespoons chimichurri over the meat, add salsa criolla if using, and serve hot with extra chimichurri on the side.
