In a large skillet, heat 2 tablespoons of olive oil and 1 tablespoon of butter over medium-high heat.
Add half of the bread cubes and toast until golden brown on most sides. Repeat with remaining oil, butter and bread cubes. Place all toasted bread cubes into a large bowl.
Add garbanzo beans, roasted red peppers, mozzarella, salami, tomatoes and fresh basil, stirring to combine.
In a small bowl whisk together olive oil, red wine vinegar, Dijon, Italian seasoning, salt and pepper.
Pour dressing over bread mixture, stirring well to combine. Serve sprinkled with Parmesan cheese. Enjoy!
