"Thaw tomatoes, puree in blender. Saute onion and garlic in olive oil until crisp tender. Using a large dutch oven saucepot, add tomatoes, seasonings and sauteed garlic and onions. Heat on medium to boiling, reduce heat to low, cover and simmer for at least 2-3 hours, stirring every 15-20 minutes.At this point, if thicker consistency is desired, remove lid and up heat to medium , stirring until more liquid is absorbed. The longer this simmers the better it is. When done you can either jar into quarts and process according to jar manufacturer directions, or let cool completely and ladle into quart freezer bags and freeze. Add hamburger or other meats to sauce before serving. Great on any pasta dish!"
