“I got the recipe for this sauce in a recipe exchange and wish I could credit the person who gave it to me,” says Meg Fisher of Marietta, Georgia. “My children love it! I added mushrooms, but if you'd like it even chunkier, add some bell pepper and other veggies, too.”
In a large nonstick skillet, cook the beef, mushrooms and onion over medium heat until meat is no longer pink; drain. Transfer to a 3-qt. slow cooker.
Stir in the tomatoes, tomato paste, tomato sauce, broth, parsley, brown sugar, basil, oregano, salt and pepper. Cover and cook on low for 6-8 hours. Serve with spaghetti. Sprinkle with cheese if desired.
