Crockpot Lasagna

1 pound Italian sausage (Replace meat with spinach for a healthier option)
1 onion, chopped
2 teaspoons minced garlic
jar of spag sauce 35 plus ounces
1 1/2 teaspoons salt
1 teaspoon dried oregano
1 (12 ounce) package  lasagna noodles (I like wheat)
12 ounces cottage cheese
1/2 cup grated Parmesan cheese
16 ounces shredded mozzarella cheese

How to make it :

In a large skillet over medium heat cook the Italian sausage, onion, and garlic until brown.
Then drain fat.
Add the tomato sauce, tomato paste, salt, and oregano and stir.
(You can also use jar sauce here or your home made sauce)
In a large bowl mix together the cottage cheese, grated Parmesan cheese, and shredded mozzarella cheese.
I prefer to mix in some provolone as well
 Spoon a layer of the meat mixture onto the bottom of the slow cooker.
Add a double layer of the uncooked lasagna noodles.  Add some of  the cheese mixture.
Repeat the layering of sauce, noodles, and cheese until all the ingredients are used.
Cover, and cook on LOW setting for 4 to 6 hours.
