Argentinian Beef Burger with Slow-Cooked Chimichurri

Method

1. In a small bowl, combine parsley, cilantro, garlic, vinegar, salt, and pepper to make a base chimichurri sauce.
2. Transfer the chimichurri to a small saucepan and heat over low heat, gently simmering for 15 minutes to allow the flavors to meld and deepen.
3. Heat a skillet over medium heat and add olive oil.
4. Cook the ground beef in the skillet until browned, about 5 minutes.
5. Form the beef into 2 patties and cook until desired doneness, about 4-5 minutes per side.
6. Toast the sesame seed buns and assemble the burger with lettuce, tomato, and chimichurri.
7. Check that the ground meat reaches 71°C (160°F) throughout before serving.
