Toast the croutons. Heat oven to 375°F. Arrange the baguette slices on an even layer on a small baking sheet or wire rack. Mist evenly with olive oil, then sprinkle evenly with the garlic salt and plenty of black pepper. Bake for 10 minutes or until crisp and lightly golden. Transfer the baking sheet to a wire rack until the croutons are cool enough to handle, then break into smaller pieces.
Toss. Combine the lettuce, croutons and dressing in a large mixing bowl and toss until evenly coated. Add in the crumbled bacon, avocado, Parmesan, chives, and briefly toss to combine.
Serve. Serve immediately, garnished with some extra black pepper, and enjoy!
Notes
Adding rosemary to the dressing: As mentioned above, I love adding in 3/4 teaspoon of rosemary powder (or 1 scant tablespoon finely-chopped fresh rosemary) to this dressing. But feel free to leave out the extra rosemary if you prefer.
