Preheat oven to 400 degrees F. While the oven is preheating, slice the bell peppers in half lengthwise and remove the seeds and stem. Place the peppers in a 9×13” casserole dish and drizzle them with olive oil and sprinkle on salt and pepper.

Heat a large skillet on medium-high heat. Pour a thin layer of olive oil in the pan – just enough to coat the bottom and generously salt and pepper both sides of the sausage. Break apart the sausage as it cooks and cook until it is nicely browned. Set aside when sausage is done.

Add the onions and garlic to the same pan and cook for 2-3 minutes. Reduce heat to low and add the sausage back to the pan along with dried oregano and pizza sauce. Simmer until the sauce is reduced and thickened.

Remove pan from heat and let cool for a few minutes. In the same pan add turn off heat, let the mixture cool slightly. Slice pepperoni into fours and add it to the same pan along with mozzarella cheese and mix together.

Spoon the mixture inside each pepper and bake for 20 minutes or until peppers are roasted and soft. Remove from oven and top the peppers with remaining shredded mozzarella cheese, sliced pepperoni and Italian seasoning bake for another 25 minutes or until cheese is browned and bubbling.

Serve immediately!
