Instructions:
1. Heat the vegetable oil in a large pan over medium-high heat. Add the sausages and cook until browned on all sides. Remove the sausage from the pan and set aside (it doesn’t need to be fully cooked yet).
2. Add the onions and peppers to the pan, cooking over medium heat until softened. Add the garlic and cook for 1 minute.
3. Slice the sausage into 1 to 1 1/2-inch pieces.
4. Return the sausage to the pan along with the tomato paste, diced tomatoes, salt, oregano, basil, black pepper, and red pepper flakes.
5. Cook for 5 to 10 minutes, until the sausage is fully cooked and the sauce has thickened.
6. Serve on hoagie rolls for an extra touch. Enjoy!
