1. In a large fry pan, over medium heat, brown the ground beef until mostly cooked through.
2. Transfer the beef to a slow cooker and add the remaining ingredients, except for the ricotta, lasagna noodles, spinach, and the parmesan. Mix well and set the slow cooker to low for 5 hours.
3. In the last hour add the ricotta cheese, spinach, and the quick cooking lasagna noodles (broken up).
4. Serve with a sprinkle of fresh grated parmesan cheese and some dried red chili flakes. Enjoy!
