Chopped onion and two cloves garlic, minced. Saute lightely. Add 8 oz. Can tomato sauce. Bring to a boil Add cauliflowerets. Simmer 15 - 20 minutes. Serve hot or cold.
the oven for the two hours until we ate; it held up fine. I felt it needed a little more sauce and a little more kick - I added a squirt of ketchup and it added that little something.
