Preheat oven to 350°. Grease 9 x 13-inch baking pan. Heat vegetable oil in large skillet over medium-high heat. Add sausage, onion, bell peppers and garlic. Cook, stirring to break up sausage, 7 to 10 minutes, or until sausage is no longer pink; drain. Combine bread cubes, cheese and sausage mixture in large bowl. Beat evaporated milk, pumpkin, eggs, pepper, oregano, basil and marjoram in medium bowl. Pour over bread mixture, pressing bread into milk mixture. Pour into prepared baking pan. Bake for 35 to 45 minutes, or until set. Serve warm. Can be prepared ahead and refrigerated. Adjust baking time as needed. Turkey sausage may be substituted, but will require more spices.
