01 - Cook bacon in a large skillet over medium heat until crispy, approximately 6–8 minutes. Remove and drain on paper towels. Crumble once cooled.
02 - Season chicken breasts with salt and black pepper. Cook in the same skillet over medium heat for 6–8 minutes per side until fully cooked through. Let rest for 5 minutes, then slice into thin strips.
03 - In a small bowl, whisk together mayonnaise, Greek yogurt, lemon juice, Dijon mustard, salt, and pepper until smooth and well combined.
04 - In a large salad bowl, combine chopped romaine lettuce, halved cherry tomatoes, diced avocado, and thinly sliced red onion.
05 - Arrange sliced chicken and crumbled bacon over the vegetable mixture.
06 - Drizzle the prepared dressing evenly over the salad. Toss gently to coat all ingredients without damaging the vegetables.
07 - Sprinkle with chopped fresh chives or parsley if desired. Serve immediately while chicken is still warm and vegetables are crisp.
