1. Cook Pasta: Bring a large pot of salted water to a boil. Cook the pasta until al dente, according to the package instructions. Reserve 1/2 cup of the pasta cooking water, then drain the pasta.

2. Cook Sausage: In a skillet over medium heat, heat 1 tablespoon of olive oil. Add the sausage and cook, breaking it into small pieces, until browned. Stir in 1 tablespoon of tomato paste and cook for 1–2 minutes. Remove the sausage from the skillet and set it aside.

3. Sauté Vegetables: In the same skillet, add the remaining olive oil, the sliced onion, and bell peppers. Cook until the vegetables are softened, about 6–7 minutes. Stir in the garlic and cook for 1 minute.

4. Build the Sauce: Add the remaining tomato paste, brown sugar, oregano, and balsamic vinegar to the skillet. Stir and cook for 2 minutes. Return the cooked sausage to the skillet.

5. Combine Pasta: Add the cooked pasta and the reserved pasta water to the skillet. Toss everything together until the pasta is coated in the creamy sauce.

6. Serve: If desired, garnish the Sweet Pepper and Sausage Pasta with toasted breadcrumbs. Serve hot and enjoy!
