Make this classic salad even easier: Use half a store-bought rotisserie chicken instead of roasting chicken breasts at home. (Cook two extra eggs, and reserve some of the shredded chicken to make Cobb Salad Sandwiches tomorrow.)
Preheat oven to 425 degrees. On a rimmed baking sheet, drizzle chicken with 1 tablespoon oil and season with salt and pepper. Roast until cooked through, about 25 minutes. Transfer chicken to a cutting board and let sit until cool enough to handle. Remove skin and discard. With your hands or two forks, shred chicken. Reserve half (1 cup) for Cobb Salad Sandwich.
Quarter 2 eggs and reserve 2 eggs for Cobb Salad Sandwich. In a large bowl, combine lettuce, lemon juice, and 2 tablespoons oil. Season with salt and pepper, toss to combine, and top with eggs, bacon, tomatoes, cheese, avocado, and remaining chicken.
