Drizzle with olive oil and top with parsley and croutons, if using.
Notes
To make croutons, preheat oven to 375 degrees. In a medium bowl, combine 2 cups bread cubes and 1 tablespoon olive oil. Season with salt and a pinch of dried chili flakes and toss to coat. Spread in a single layer on a baking sheet and bake for 15 minutes or until golden brown and crispy, stirring halfway through. Let croutons cool completely before using.
