As an American of Italian descent, I have a few ideas on best spaghetti sauce. Fresh is always best, BUT some really quick (easy and inexpensive) ways to get a great spaghetti sauce goes like this.
1. With coupons or on sale take advantage of the large cans of tomatoes sauce, chunky or pureed are great!
2. Saute onions with a little garlic, pinch of salt and pepper in canola oil (MUCH less expensive than olive)!
3. In a slow cooker, add the sauteed ingredients, a couple of cups of water OR chicken stock. Add the canned tomatoes, some Italian seasonings, fresh or dried basil (whatever your pantry has on hand).
4. Slow cook on low for a few hours (depending on how much sauce you are yielding).
5. Store and freeze for the future! VOILA the best sauce, to me is made at home! YOU have a control on the ingredients, the sodium, etc. In addition, could be easily made in the slow cooker while you are doing something else!
PS on the day you make it, simply boil up your favorite pasta, make a salad and crusty bread for your first dinner's worth!
Hope this helps!
