Would I post something that did not contain sugar? Probably not. After the sauce simmered for a while, it needed something. I added sugar!
2 - 28 oz cans San Marzano whole tomatoes and juice (squish these with your hands)
2 teaspoons home made pesto (could have used more)
1 onion chopped and sauteed in 1/2 stick butter
1 large bay leaf
2 - 3 teaspoons kosher salt, to taste
1 teaspoon Penzeys Tellicherry Black Pepper
1 teaspoon garlic powder
2 teaspoons dried oregano
2 teaspoons Penzys California Sweet Basil
3 tablespoons sugar
Let simmer for 3-4 hours.
