In a large bowl, mix together beef, Bertolli® sauce, cottage cheese, and 1 cup of Mozzarella Cheese.
Add a layer of the beef mixture in the bottom of the crock pot.
Add layer of UNCOOKED lasagna noodles. You may need to break the noodles to allow them to fit.
Continue adding a layer of beef mixture and noodles until you use all the beef mixture. Make sure the beef mixture is the last layer.
Cover with the remaining Mozzarella Cheese.
Turn your crock pot to low for 3 hours. My crock pot cooks hotter than most and it did not take the full 3 hours. You will know when it is done by checking the lasagna noodles to see if they are tender.
