Soak each matzah in hot water for 30 seconds and set aside.
Mix the cottage cheese, parmesan, mozzarella and egg together. Leave a small amount off parmesan and mozzarella aside to sprinkle on top.
Lightly grease a square 8-inch pan.
Spread a small amount of tomato sauce on the bottom of the pan and place one matzah on top of the sauce.
Spread 1/3 of the cheese mixture on the matzah and spread. If you are adding any sautéed vegetables spread some on top of the cheese layer and then cover with more tomato sauce.
Continue placing the ingredients in the same order: Matzah, cheese, sautéed vegetables, and tomato sauce. After you have spread the last layer of tomato sauce sprinkle the remaining mozzarella and parmesan cheese on top.
Bake at 350F for about 45 minutes until golden on top, let sit for 10 minutes before serving.
