Step 1: Cook the Chicken : Season chicken breasts with salt, pepper, and a drizzle of olive oil. Grill or pan-sear for 6–7 minutes per side (depending on thickness) until cooked through and golden. Set aside to rest for a few minutes, then slice thinly.
Step 2: Prepare the Bacon and Eggs Cook bacon in a skillet until crisp, then drain on paper towels and crumble. Hard-boil eggs (place in boiling water for 9–10 minutes), cool, peel, and quarter.
Step 3: Make the Blue Cheese Dressing : In a bowl, whisk together mayonnaise, sour cream, milk, lemon juice, and Worcestershire sauce. Stir in crumbled blue cheese and mix until creamy (you can leave it chunky or blend for smoothness). Season with salt and pepper to taste. Refrigerate until ready to use.
Step 4: Assemble the Salad : On a large serving platter or salad bowl, spread the chopped lettuce as the base. Arrange sliced chicken, bacon, eggs, avocado, tomatoes, and blue cheese in neat rows over the greens. Sprinkle chives or green onions on top for freshness.
Step 5: Dress and Serve : Drizzle the salad with blue cheese dressing right before serving, or serve dressing on the side. Toss gently if desired, and enjoy immediately.
