Preheat oven to 400F degrees. Spray a Bundt pan with nonstick cooking spray.
Cut each biscuit into 4 pieces, place in a bowl. Toss biscuit pieces with 1 Tablespoon olive oil and set aside.
In a separate bowl, combine 16 slices pepperoni, quartered, 1 ½ cups shredded mozzarella cheese, ¼ cup grated Parmesan cheese, 1 teaspoon Italian Seasoning, 1 teaspoon onion powder and ¼ teaspoon garlic salt; mix well.
Add the quartered biscuits; toss well to coat.
Arrange in the prepared Bundt pan.
Bake on the middle rack at 400F degrees for 15 minutes (or until golden).
Turn bread out of pan onto a serving plate and serve with pizza sauce while still warm.
