Preheat oven to 400ºF and spread the olive oil on the bottom of a cast iron (or oven-safe) skillet.

Cut each of the 3 tortillas in half. Take a half tortilla and spread the bottom with roughly 1 tablespoon of ricotta in a triangle shape (like a slice of pizza) in the center of the tortilla half. Top with 1 tablespoon of marinara sauce, 2 tablespoons of cooked ground sausage, 2 tablespoons of shredded mozzarella cheese, and 2 basil leaves. Fold both ends of tortilla over the filling, forming a triangle. Add the pizza pocket, folded tortilla side-down, to the oiled skillet. Continue building the triangles, placing them into the pan like pizza slices forming a circle.

Cook over medium heat on the stove for about 3-4 minutes, carefully lifting the tortilla to check that the underside is golden brown and crispy. Top the tortillas with the remaining ½ cup shredded mozzarella. Transfer the pan to the oven and bake for 5 minutes. If the cheese isn’t brown and edges of the tortillas golden brown and crispy, broil on high heat for 1-2 minutes. Top with oregano leaves or fresh basil and enjoy.
