Creating the perfect Peruvian Chicken with Green Sauce is a breeze if you follow these simple steps:

1. Prepare the Marinade: In a bowl, whisk together olive oil, white vinegar, minced garlic, cumin, paprika, salt, and black pepper.
2. Marinate the Chicken: Place the chicken breasts in a large resealable bag. Pour the marinade over the chicken, seal, and massage to coat evenly. Let marinate for at least 30 minutes (or overnight for best results).
3. Prepare the Green Sauce: In a blender, combine cilantro, jalapeños, mayonnaise, lime juice, and ground pepper. Blend until smooth. Adjust seasoning as needed. Set aside.
4. Preheat the Grill: Heat the grill to medium-high heat.
5. Grill the Chicken: Remove the chicken from the marinade, allowing excess to drip off. Place the chicken on the grill and cook for about 6-8 minutes on each side or until it reaches an internal temperature of 165°F (75°C).
6. Rest the Chicken: Once cooked, remove the chicken from the grill and let it rest for a few minutes before slicing.
7. Serve with Sauce: Serve the sliced chicken drizzled with the green sauce, either on the side or generously over the top.

By following these steps, you’ll create a dish that is both flavorful and visually appealing, perfect for any occasion.
