If you'd like, you can cool this sauce in the refrigerator and then separate it into bags or containers to freeze. It thaws relatively quickly, and then you have delicious slow-cooked tomato sauce any night of the week.
When using canned tomatoes, I like to add a little bit of sugar. It doesn't sweeten the sauce, but it does cut down on the acidic taste that canned tomatoes can sometimes have. Add in more if you'd like a sweet sauce (but not more than a tablespoon), or leave it out completely.
