Brown meat in a large skillet and drain
Add spices and pour in the entire jar of pasta sauce.
Simmer on low for a few minutes.
In your crockpot put a ladle-full of sauce mixture into the bottom. about 1 cup
Top with a layer of uncooked lasagna noodles (break them to fit).
Next top with cheese. (ricotta then shredded seems to work best for me)
Add another layer of noodles, sauce, and cheese, and repeat until you use all the noodles end with the meat sauce on top.
Add 1/4 cup of water to the pasta sauce jar.
Shake and pour over mixture.
Cook on low for 8 hours or high for 4 hours.
Once it is done cooking ass any remaining shredded cheese to the top and let it sit with the lid on for 10-15 minutes or until the cheese is melted. I put the Ninja Foodi on keep warm for about 10 minutes and it was perfect.
