Meat Sauce with Hidden Vegetables

Instructions

1. 1
   Heat olive oil in a large pot over medium heat. Add onion, carrots, zucchini, and bell pepper. Sauté for 5 minutes until softened. Add garlic and cook 1-2 more minutes.
2. 2
   Add ground beef. Cook, breaking it up with a spoon, until browned and no longer pink, about 5-6 minutes. Drain excess fat if needed.
3. 3
   Stir in tomato paste, oregano, basil, salt, black pepper, and red pepper flakes. Cook for 2 minutes to develop flavor.
4. 4
   Add crushed tomatoes, water (or broth), and sugar (if using). Stir well, bring to a gentle simmer, then reduce heat to low. Partially cover and simmer for 20-25 minutes, stirring occasionally.
5. 5
   Stir in balsamic vinegar, taste, and adjust seasoning. Serve over pasta, garnished with parsley and Parmesan.
