In a large spotlessly clean stainless steel bowl, beat egg whites to stiff peaks with cream of tartar. Set aside.
Meanwhile, combine remaining ingredients except for noodles and tomato paste. Gently fold egg whites into cheese mixture.
Lay 6 noodles in the bottom of a roasting pan. Add a layer of tomato sauce, then cheese mixture, then more noodles. Repeat 1 more time.
Spread some more tomato sauce on top then add more cheese mixture on top. Cover with aluminum foil and bake at 375° for 15 minutes. Remove foil and bake for another 20 minutes. Remove and let rest for 10 minutes. Serve.
