Puree the onion, carrots and celery. Add puree to hot saute pan with evoo and cook on high, stirring to release the natural juices and cook until tender, about 5 minutes. Place aside in large pot until later.

Brown ground chuck and drain excess grease. Add the Italian seasoning, salt and pepper and pepper flakes and balsamic vinegar to the cooked beef. Mix cooked beef to the puree.

Build your mountain of lasagna now. Spray inside crockpot with cooking spray or oil to prevent sticking. Cover the bottom of crockpot with meat/sauce mixture. Then add a layer of uncooked lasagna noodles (breaking them to fit and overlapping is good). Then add enough cheese mixture to cover the noodles (you can use a spatula to spread it evenly ). Then add more noodles, then cheese mixture, then meat/sauce, and finally end with meat sauce on top. Make sure all of the noodles are covered in sauce to prevent drying out. Sprinkle some parmesan cheese on top. When it's almost done, an hour or 30 mins before add a layer of mozzarella cheese and provolone cheese to the top so it can melt and be more gooey and yummy. :-p Cook on low for 6-8 hours or high for 4-6 hours (depends on size of crockpot and how long you are willing to wait.
