This restaurant-style recipe features juicy pork tenderloin marinated in a blend of garlic, herbs, and spices, then grilled to perfection and served with a zesty chimichurri sauce. The tenderloin is first rubbed with a mixture of garlic, cumin, smoked paprika, and olive oil, then grilled until it's nicely charred on the outside and juicy on the inside. The chimichurri sauce is made with fresh parsley, cilantro, garlic, red wine vinegar, and olive oil, and adds a bright, tangy flavor to the dish. Serve with grilled vegetables or a side salad for a delicious and healthy meal.
