Preheat oven to 400 degrees. Brown the sausage over medium-high heat. Season with red chili pepper flakes. Roll out the pizza dough on a lightly floured surface, creating a large rectangle. Using a slotted spoon, in case there is any liquid or fat that was rendered while cooking, transfer the sausage to half of the dough, allowing enough dough to roll it up like a jelly roll. Tuck the ends under. Drizzle EVOO over the entire roll, Sprinkle with sea salt flakes. Add a small amount of EVOO to a baking sheet, so the roll does not stick to the pan. Transfer the roll to the greased baking sheet. Bake for about 20 minutes, or until golden brown. Allow to cool for 5 minutes before slicing. Serve immediately.
