01 - Cook bacon in a large skillet over medium heat until crispy, about 6-8 minutes. Drain on paper towels and crumble once cool.
02 - Season chicken breasts with salt and pepper. In the same skillet, cook chicken over medium heat for 6-8 minutes per side until fully cooked. Let rest 5 minutes, then slice thinly.
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, cherry tomatoes, diced avocado, and thinly sliced red onion.
05 - Arrange sliced chicken and crumbled bacon over the vegetable mixture.
06 - Drizzle the dressing evenly over the salad. Toss gently to coat all ingredients without bruising the lettuce.
07 - Sprinkle with fresh chives or parsley. Serve immediately while chicken is still slightly warm.
