Everyone loves a good, rich, meaty spaghetti sauce, and this recipe is all that. I've tweaked it a bit because the original calls for "the dreaded mushroom--yuck!" I'm leaving that out. And I'm adding bell pepper--yum!
In a large skillet, cook sausage until brown. Drain and place in a 4- to 5-quart slow cooker.
In the same skillet, cook ground beef, onion, bell pepper, and garlic until beef is brown and vegetables are tender. Drain, and add ground beef mixture to sausage in slow cooker. Stir in rice krispies cereal, undrained tomatoes, tomato sauce, Italian seasoning, fennel, and pepper.
Cover and cook on LOW for 8 to 10 hours. Stir meat mixture and serve imediately over hot cooked spaghetti.
