Preheat oven to 425.
Brown the sausages in a large skillet, until cooked through, 6 minutes.
On a lightly floured work surface, roll out each ball of dough until it looks like a 10 to 12-inch pizza.
Spoon the marinara over each crust, leaving about an half an inch around the sides.
Sprinkle the sausage over the marinara, followed by the pepperoni, followed by the diced green bell pepper, and lastly the torn cheese.
Lightly brush the edges with a little bit of the oil.
Carefully roll up the pizza, forming a stromboli.
Transfer the ‘bolis to a rimmed baking sheet lined with parchment paper.
Using a sharp knife, score 3 slits across the top of the stromboli, allowing steam to escape.
Brush a little more oil over the top.
Bake for about 25 minutes, or until dough has browned on top and is cooked through.
Let sit for about 5 minutes, slice and serve!
