Heat oil in a large skillet over medium heat. Add sausage, onion, and garlic and cook until sausage is brown, about 6-8 minutes. Add Dei Fratelli Seasoned Diced Tomatoes and heat through, about another 2 minutes.
In a large bowl, mix together bread cubes, tomato mixture, and parmesan cheese until well combined. Set aside.
In a medium bowl, whisk together eggs, milk, salt, and pepper. Pour over bread mixture and gently toss together.
Place finished mixture into a greased 9x13 baking dish. Bake for 25-30 minutes, or until golden brown.
