Prepare the Herbs: Pulse the parsley and cilantro in a food processor until finely chopped.
Blend the Sauce: Add the remaining ingredients to the food processor and blend until smooth.
For the Steak Kebabs:
Marinate the Steak: Cut the steak into cubes and marinate in half of the chimichurri sauce for at least 30 minutes. This allows the flavours to penetrate the meat, making it tender and flavourful.
Assemble the Kebabs: Thread the marinated steak cubes onto skewers.
Grill the Kebabs: Preheat the grill to medium-high heat. Grill the kebabs for 8-10 minutes, turning occasionally, until the steak is cooked to your desired doneness.
Serve: Drizzle the remaining chimichurri sauce over the grilled kebabs before serving.
