01 - Rub chicken breasts with 1 tablespoon olive oil, 1/2 teaspoon salt, and 1/4 teaspoon black pepper, ensuring even coating on all sides.
02 - Heat a grill pan or skillet over medium-high heat. Grill chicken for 6 to 7 minutes per side until internal temperature reaches 165°F and juices run clear. Transfer to a plate and let rest for 5 minutes before slicing into strips or dicing.
03 - In a large mixing bowl, combine diced avocados, halved cherry tomatoes, sliced red onion, chopped cilantro or parsley, diced cucumber, and mixed salad greens.
04 - In a small bowl, whisk together 3 tablespoons extra-virgin olive oil, lime juice, Dijon mustard, minced garlic, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until fully emulsified and thickened.
05 - Add sliced chicken to the vegetable mixture. Drizzle dressing over the top and toss gently with salad tongs to combine, taking care not to mash the avocados.
06 - Plate immediately and garnish with additional fresh herbs if desired. For variation, serve in lettuce wraps for a low-carb presentation.
