In a large skillet cook sausage until browned. Drain off fat; set aside. Meanwhile, in a medium bowl combine cottage cheese, green onions, chives, and carrot; set aside.
In a very large bowl whisk together eggs, milk, salt, and pepper. In a large skillet melt butter over medium heat; pour in egg mixture. Cook over medium heat, without stirring, until mixture begins to set on the bottom and around the edge. Lift and fold the partially cooked egg mixture so the uncooked portion flows underneath. Continue cooking over medium heat for 2 to 3 minutes or until egg mixture is cooked through but still glossy and moist. Immediately remove from heat.
In a small bowl combine the Alfredo sauce and Italian seasoning. Spread about 1/2 cup of the sauce mixture over the bottom of a 3-quart rectangular baking dish. Layer half of the lasagna noodles in the dish, overlapping as necessary. Top with half of the remaining sauce, half of the cottage cheese mixture, half of the hash browns, half of the scrambled egg mixture, and half of the sausage mixture (see photo 3). Sprinkle with half of the cheese. Repeat layers.
Cover dish tightly with plastic wrap. Refrigerate for 8 hours or overnight.
Remove from refrigerator and let stand at room temperature for 30 minutes before baking. Preheat oven to 350 degrees F. Remove plastic wrap and cover dish with foil. Bake for 45 minutes. Remove foil and bake 15 minutes more or until heated through. Let stand for 5 minutes before cutting into portions.
