Cook the noodles to desired doneness (al dente recommended.) They will cook more in the slow cooker so do not overcook them.
Spray your slow cooker with cooking spray and combine all ingredients in the slow cooker.
Stir to thoroughly combine.
Cook on low for 2 1/2-3 hours, stirring occasionally while it's cooking.
When done cooking, serve hot. Top with fresh basil (optional.)
