Preheat your oven to 400 degrees.
Start by bringing 1 tbsp olive oil to medium heat in a large sauce pan. Sauté your onion and pepper until translucent. Add in garlic and cook another minute.
Add in sausage and crumble. Cook until brown, about 5 minutes. I like to keep mine in bite sized chunks. Stir in your Italian seasoning, red pepper flakes and salt and pepper.
Pour in your water and sauce and bring to a boil.
Add in your pasta and cover and turn heat to low. Cook for 20 minutes. Stirring every 5 mintues until pasta is cooked through. If all liquid is absorbed and pasta is not cooked add 1/2 cup water and cook until pasta is cooked!
Top with mozzarella cheese and pepperoni. Sprinkle with red pepper flakes and oregano. Bake at 400 for 10 minutes. Or until nice and bubbly
