Used To be Dianne's Lasagna

I got a recipe from Dave's sister Dianne. She makes it every Christmas. I've tweaked it to my liking, and now it's mine, but it used to be Dianne's.

Lasagna Noodles - do not cook
8 oz cottage cheese
8 oz plain yogurt
2 jars spaghetti sauce (barilla 3 cheese)
1 lb hamburger, browned and drained
8 oz shredded Mozzarella cheese
8 oz shredded cheddar cheese (State Brand Mild Cheddar)
1Tbsp Tastefully Simple Onion Onion

Heat oven to 400 degrees. After browning and draining beef, add almost all the spaghetti sauce. If you have it, add some Tastefully Simple Onion Onion to this mixture.
In a separate bowl, mix cottage cheese with plain yogurt and cheddar cheese. In a 9 x 13 pan, layer Noodles, meat sauce and yogurt mixture. Continue layering for a total of three layers, ending with noodles and sauce. Pour remaining sauce around edges.
Cover and seal with aluminum foil so that the steam can not escape. Bake for 1 hour. Remove foil and sprinkle shredded mozzarella cheese on lasagna and return to oven (without the foil) for 15 minutes longer or until cheese melts and begins to brown. Remove from oven and let sit for 10 minutes before cutting and serving. Serves 6
