Use cooking spray to spray the bottom and sides of your crock pot
Mix together the cottage cheese, parmesan, 3/4 of the mozzarella, beans and Italian seasoning.
Take one cup of the spaghetti sauce and coat the bottom of the crock pot
Break three (raw, uncooked!) lasagna noodles to make a layer. One might lay whole but you'll have to break the others into pieces.
Spread about 1/3 of the cheese mixture followed by 1 large handful of spinach. Some people don't like eating big chunks of spinach so I recommend you chop it if that's you!
Repeat spaghetti sauce, lasagna, cheese and spinach layers two to three times.
The last layer is your can of no salt added tomato sauce over the last layer of spinach. Sprinkle the remaining 1/4 block of mozzarella cheese over the top.
Put the lid on it and let it sit on high for 2-3 hours or on low for about 3-4 hours. It doesn't take long!
