I already had some home-made meatless tomato sauce with basil, plus home-made basil pesto. I combined these sauces, but next time will make the sauce per the recipe. The other change I made was ricotta cheese instead of cottage cheese. Next time I won't pre-cook the mushrooms, as this cooks the goodness out of them, but also increase the cooking time at 350 F to 30 to 40 minutes. Very tasty and hearty for a meatless meal.
