Preheat the oven to 375. Lightly grease a 9x13 or just slightly smaller pan and set aside.
In a large skillet, cook the sausage and ground beef until no pink remains. Drain away any fat from the bottom of the pan and return the meat to the skillet.
Over low heat, add the marinara sauce and stir to combine. Simmer 5-7 minutes and turn off the heat.
NOTE: If your no boil noodles ask you to add a cup of water to your sauce, you can do that here. Follow the directions on your favorite brand for that.
In a small bowl, mix the cottage cheese OR ricotta, the egg, and 1 teaspoon Italian seasoning. Stir to combine.
Begin the layers: In the bottom of the pan, spread 1/2 cup of the sauce. Place a layer of noodles on top, followed by 1/3 of the cottage cheese mixture. Spread it as evenly as you can. Add another 1/2 cup of sauce, then 1/3 of the cheese, and a sprinkling of parmesan.
Repeat the layers two more times for a total of three and end with pasta sauce. Add mozzarella and parmesan on top. Sprinkle on the last teaspoon of Italian seasoning.
Spray a large sheet of aluminum foil with cooking spray and cover the lasagna. Bake 20 minutes covered, then remove the foil and bake 10 minutes more until it's hot all the way through and bubbling on the edges.
Allow to stand 10 minutes before serving.
