Preheat oven to 190C/Gas 5. Lightly oil the bottom of a 32cm by 40cm by 5cm baking dish.
In a large saute pan, over medium-high heat, add 1 tablespoon oil and saute meat, onion, and garlic until meat is browned, breaking up meat with a wooden spoon. Drain pan of fat and add stewed tomatoes, tomato sauce, and tomato paste. Cover and simmer for 15 minutes, stirring occasionally.
In a large bowl, whisk together eggs, then mix in cottage cheese, 50g Parmesan, parsley, salt, pepper, and seasoning salt.
Spread a little of the meat sauce in the bottom of the prepared pan. Lay half the noodles in the bottom of the baking dish, overlapping by 1.5cm. Spread half the egg and cottage cheese mixture evenly on top. Sprinkle half the mozzarella and Cheddar evenly over the cottage cheese mixture. Pour half the meat sauce on top. Repeat layering in same order. Sprinkle remaining 25g Parmesan on top. Bake in center of oven 30 to 35 minutes until sauce is bubbling around the edges. Let stand 10 minutes before serving.
