I work as a school aged child care site director. I love to volunteer at our local community theatre as the house manager. I have two daughters in college and three cats.
Here is a link to the basic recipe. I have Caramelized the onions as suggested however I find just roasting them with the tomatoes is easier. As always adjust the recipe to your tastes. I also add a tablespoonful of tomato paste and a dash of balsamic vinegar. Oh and a couple dollops of sour cream. Be sure and top with Parmesan cheese!
