01 - Place bacon slices in a large skillet over medium heat. Cook for 6–8 minutes, turning occasionally, until crispy and browned. Transfer to paper towels to drain. Once cooled, crumble into pieces.
02 - Season both sides of chicken breasts generously with salt and pepper. Using the same skillet with bacon drippings, cook chicken over medium heat for 6–8 minutes per side until internal temperature reaches 165°F. Remove from heat and let rest for 5 minutes before slicing into thin strips.
03 - In a small mixing bowl, whisk together mayonnaise, Greek yogurt, lemon juice, Dijon mustard, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until smooth and fully combined.
04 - In a large salad bowl, combine chopped romaine lettuce, halved cherry tomatoes, diced avocado, and thinly sliced red onion. Toss gently to distribute evenly.
05 - Arrange sliced chicken breast and crumbled bacon over the vegetable mixture.
06 - Drizzle the prepared dressing over the salad. Toss gently to coat all ingredients evenly. Garnish with chopped fresh chives or parsley. Serve immediately while chicken is still warm.
