Cook pasta for approximately 5 minutes until just before fully done (al dente).
Brown the ground meat in a skillet and drain excess fat if needed.
Combine all ingredients except the cheese in a large bowl and mix well.
Coat the slow cooker with non-stick spray or use a liner.
Add a layer of the mixture to the slow cooker, then top with a layer of cheese. Repeat for a total of 3 layers, finishing with cheese on top.
Cover and cook on low heat for 3.5–4 hours.
