Creating Grilled Chimichurri Chicken is simple when you follow these steps:

1. Make the Chimichurri Sauce: In a medium bowl, combine the parsley, cilantro, garlic, olive oil, red wine vinegar, red pepper flakes, salt, black pepper, and lemon juice. Mix well and set aside.

2. Prepare the Chicken: Pat the chicken breasts dry with paper towels. Season both sides with salt and pepper.

3. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or shallow dish. Pour half of the chimichurri sauce over the chicken, ensuring it is well coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes.

4. Preheat the Grill: Heat your grill to medium-high heat.

5. Grill the Chicken: Remove the chicken from the marinade and discard the marinade. Place the chicken on the hot grill. Grill for 6-8 minutes per side, or until the internal temperature reaches 165°F (75°C).

6. Rest the Chicken: Once cooked, remove the chicken from the grill and let it rest for about 5 minutes. This helps retain moisture.

7. Serve with Chimichurri: Slice the chicken and serve it drizzled with the remaining chimichurri sauce.

8. Garnish (Optional): Add fresh herbs or lemon wedges for an extra touch of flavor.
