Directions

1. Preheat grill. For the creamy chimichurri: Combine the parsley, basil, cilantro, olive oil, garlic, vinegar, lime juice, cumin, salt, and pepper in a blender. Process until fresh herbs are finely chopped. Add the Greek yogurt and avocado and blend until smooth and creamy. For the flank steak: Combine the chili powder, salt, and black pepper in a small bowl. Rub evenly over the flank steak. Grill steak on both sides about 4 minutes each or until preferred doneness. Transfer to a cutting board and let rest for 5 minutes (to retain juices). Cut on bias into strips. Serve with the creamy chimichurri sauce.
