Preheat oven to 375°F (190°C).
Meat Filling: Remove sausage from casing; crumble meat. In Dutch oven, cook sausage and beef over medium-high heat, breaking up with back of spoon, for about 5 minutes or until no longer pink; remove to plate. Spoon off all but 1 tablespoon (15 mL) fat from pot.
Cook onion, carrot, celery, garlic, oregano, basil and hot pepper flakes, stirring, until softened, 3 to 5 minutes. Add tomatoes, tomato sauce and meat; bring to boil. Reduce heat and simmer, breaking up tomatoes and stirring often, for 20 to 25 minutes or until thickened. Add pepper.
Cheese Filling: In bowl, beat together eggs, pepper and nutmeg. Blend in cottage cheese, mozzarella and Parmesan.
In large pot of boiling salted water, cook noodles for 6 to 8 minutes or until almost tender. Drain and place in cold water. Arrange in single layer on damp tea towel.
Spread 1 cup (250 mL) of the meat filling as base in greased 13- x 9-inch (3 L) baking dish. Top with one-third of the noodles in single layer; spread with one-third of the remaining meat filling. Spread with half of the cheese filling, then half of the spinach. Starting with noodles, repeat layers once.
Top with remaining noodles; spread with remaining meat filling. Sprinkle with mozzarella and Parmesan. Cover loosely with foil; bake for 20 minutes. Uncover and bake for 20 to 25 minutes or until bubbly and heated through. Let stand for 10 minutes before serving.
