Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a small non-stick skillet over medium heat, cook the ground turkey until fully browned and crumbled, approximately 5-7 minutes.
Season the cooked turkey with sea salt, black pepper, and garlic powder, then set aside.
Place the tortilla on the prepared baking sheet and slice the string cheese stick in half lengthwise.
Arrange the string cheese pieces around the perimeter of the tortilla, fold the edges over the cheese, and secure with toothpicks to create the stuffed rim.
Spread the tomato sauce evenly over the center of the tortilla base.
Sprinkle the shredded mozzarella cheese over the sauce, then top with the cooked ground turkey, turkey pepperoni, and Canadian bacon.
Finish with a sprinkle of dried oregano over the entire pizza.
Bake for 8-10 minutes until the crust is golden brown and the cheese is melted and bubbling.
Remove the toothpicks before slicing and serving warm.
