Preheat oven to 425°F. Grease a 14-inch round baking stone, a 12-inch pizza pan, or large baking sheet; set aside. Roll Whole-Grain Pizza Crust dough on a lightly floured surface into a 12-inch circle. Transfer to the prepared baking stone. Prick the dough all over with a fork. Bake for 6 to 8 minutes or until the crust is lightly browned.
Meanwhile, for sauce, combine tomato sauce, tomato paste, Italian seasoning, garlic, and pepper in a small bowl.
Lightly brush 1 inch of the edge of the hot crust with oil. Spread the sauce over the crust to within 1 inch of the edge. Top with cooked ground beef and Canadian bacon. Add mushrooms and olives; sprinkle with cheese.
Bake for 8 to 10 minutes more or until the cheese is melted and the vegetables are softened.
