First, set oven to 375 degrees.
Brown the ground beef and sausage with the onion and the garlic.
Drain the meat mixture.
Next, put the meat back into the skillet along with the can of diced tomatoes, the tomato paste, and the Italian seasoning. Cover and simmer for about fifteen minutes.
While the meat mixture simmers, beat three eggs in a medium-size mixing bowl.
Add the cottage cheese, the chopped parsley, the grated parmesan cheese, and the salt and pepper to the eggs. Mix well.
Layer half of the no-boil lasagna noodles on the bottom of a baking dish.
Ladle about half of the cottage cheese mixture over the noodles.
Next, carefully spread half of the meat mixture over the cottage cheese.
Spread one cup of cheddar and one cup of mozzarella over the meat.
Repeat layers so that you end up with two layers of everything, with cheese on top.
Bake the dish for about 35-40 minutes until the cheese looks perfectly golden.
About five minutes before lasagna is set to come out of the oven, pull the lasagna out and sprinkle one cup mozzarella cheese on top. Put lasagna back in oven to finish baking.
Allow lasagna to cool five minutes or so before serving.
