Robin's Crockpot Lasagna

We have a 4 qt crockpot (I think that's right) and this recipe was a little bit too much for it...you can adjust accordingly for whatever size crockpot you have and how much your family eats. I also thought there was too much meat in ours, but you know me and ground beef: we don't always get along....Over all, I thought the dish was delicious and Bryce liked it too. It's a great meal to prepare for Sunday...get it all ready (you can even leave it in the fridge overnight, the noodles won't get soggy) and then turn the crockpot on before you leave for church and it's ready when you get home.

Ingredients:
1 1/2 lb ground beef
1 medium onion, chopped
jar of spaghetti sauce (Prego's Traditional is my personal favorite)
can of tomato sauce (optional)
1 clove garlic, minced (I used a garlic press for the first time! This probably made me more excited than it should have)
salt and pepper (to taste)
4 cups shredded cheese (your choice: mozzarella and cheddar are recommended)
1 1/2 c cottage cheese
1/2 c parmesan cheese
lasagna noodles (doesn't matter what kind)

Directions:
Cook lasagna noodle according to directions on box (we used about half a box)
In large saucepan saute onion
Add beef, garlic, and salt & pepper
After the beef is browned, add jar of spaghetti sauce
In medium bowl, combine the three types of cheese
Spread a layer of tomato sauce(This is where the optional can of tomato sauce comes in: you can either save out some of the spaghetti sauce or you can use tomato sauce) in bottom of crockpot (You may want to line the crockpot with tin foil or spray with Pam first for easier clean up)
Layer noodles, cheese, and meat 3 times
Top with noodles, and then top with cheese and tomato sauce (or just tomato sauce)
Cook on low for 3-4 hours
