Toast the bread cubes: Spread the bread cubes on a baking sheet and bake at 375°F (190°C) for 10-15 minutes, or until golden brown and crispy. Let cool.
Prepare the vinaigrette: In a small bowl, whisk together olive oil, red wine vinegar, minced garlic, salt, and pepper.
Combine ingredients: In a large bowl, combine the toasted bread, cherry tomatoes, cucumber, red onion, bell pepper, basil, and parsley.
Dress the salad: Pour the vinaigrette over the salad and toss gently to coat. Let sit for at least 10 minutes before serving to allow the flavors to meld.
Serve: Serve chilled or at room temperature.
Notes
This Panzanella is best enjoyed the day it's made. You can add other vegetables like olives or capers for extra flavor.
