Heat a non stick pan then cook the sausage until just cooked through, breaking it up with your spatula, drain the fat and place on paper towels.
While the sausage is cooking, prep and get all the remaining ingredients. Preheat your oven to 220° C (425° F). Line a baking sheet with foil.
On the prepared baking sheet, lightly floured, roll out the dough to about an 8 inch circle, we're not looking for precision or a perfect circle here, just eyeball it. Lightly brush the dough with some olive oil.
Starting in the center of the dough, add the pizza sauce and spread into a 6 inch circle. The extra dough, we'll get to that in a few minutes.
Place the Italian sausage on the pizza sauce.
Place the Provolone cheese on the sausage.
Place the Canadian bacon on top of the cheese.
Add the Parmesan cheese on top of the Canadian bacon.
Add the Mozzarella cheese then the Parmesan cheese, followed by the pepperoni.
Now for that extra dough, take a knife and cut the dough from the edge of the pizza sauce out to the edge about every 2 inches, so it looks like spokes on a bike wheel.
Fold the extra dough over the pizza fillings, brush with olive oil and sprinkle with some dried oregano.
Place the pizza galette on the prepared baking sheet and bake for 12-18 minutes, goal is cheese lightly browned and bubbly.
Remove from the oven, slice, and serve.
