Creating Peruvian Chicken with Green Sauce is straightforward if you follow these simple steps:

1. Prepare the Marinade: In a large bowl, whisk together the olive oil, white vinegar, minced garlic, cumin, paprika, salt, and black pepper.
2. Marinate the Chicken: Add the chicken breasts to the marinade, ensuring they are fully coated. Cover and refrigerate for at least 1 hour.
3. Blend the Green Sauce: In a blender, combine the cilantro, parsley, jalapeño, Greek yogurt or mayonnaise, and lime juice. Blend until smooth and set aside.
4. Preheat the Oven: Preheat your oven to 375°F (190°C).
5. Bake the Chicken: Place the marinated chicken breasts on a baking sheet lined with parchment paper. Bake for 25-30 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
6. Serve with Sauce: Once the chicken is done, remove it from the oven and let it rest for a few minutes. Slice the chicken and serve it drizzled with the vibrant green sauce.
