Cut the baguettes lengthwise without cutting through completely. Spread some butter and bake the bread for 5 minutes at 180ºC (350ºF).

Cut the sausages lengthwise without cutting through completely. Cook them in a grill or a cast iron pan until both sides are brown and fully cooked. About 5 minutes each side over medium heat.

In a food processor toss all the ingredients for the chimichurri sauce and process for a minute or less in medium speed. It is important that you check that the onion is still in small chunks and not blended into the sauce. Try to stop every few seconds to check. The sauce must have small chunks of onion, garlic, and parsley. You can check the picture above for reference.

Fill the baguettes with the sausages and cover with chimichurri. Enjoy!
