Heat the olive oil in a medium skillet over medium heat. Add the onion, bell pepper, parsley, garlic, jalapenos (if using), sugar and Italian seasoning. Cook, stirring frequently, until veggies are soft, about 4 to 5 minutes.
Add the cooked veggies to a crockpot, along with the tomato sauce, pasta sauce and meatballs. Cook on Low heat for 7 to 8 hours or High heat for 4 to 5 hours.
Serve over cooked spaghetti noodles and top with Parmesan cheese. Enjoy!
Notes
Pour extra sauce over meatballs, then top with grated Parmesan cheese, freshly ground black pepper and fresh parsley!
Jalapeno peppers are optional. Only add them if you are up for a bit of a spicy end result.
Green bell peppers add such a nice crunch and flavor to the final dish. If you have red or orange bell peppers on hand, feel free to use those instead.
If the sauce is too thick, thin it out with beef broth or extra tomato sauce.
