It is called Contadina spaghetti sauce. They also have the large cans of tomato sauce etc... but look for the spaghetti sauce. It isn’t like some of the store brands that have a lot of sugar in it. It is more like the homemade Italian style that is a bit more bitter. If you like it sweeter, you simply add more sugar. It is a great size because you simply freeze any leftovers and they are ready for a quick meal simply because you cook the pasta. Mom
You can also use a small amount of vinegar to cut that bitterness. That way you don’t bring in any extra sugar if you are watching sugar.
First, grate onion. I use a box grater. The grating releases more flavor. Saute that in butter for about ten minutes until the onion is well done. Chop (or mince) some garlic and add it.
Here I add a couple of Tbs of olive oil and a couple Tbs of an Italian spice mix we have on the shelf plus a good grind of pepper. Let the dried spices get nice and incorporated.
Then add a can (or two or three) of crushed tomatoes. My preferred brand is Muir Glen. I find the flavor way superior to other brands.
Let that come to a boil, then simmer for a few minutes. When we have it, I add fresh basil and parsley at the very end.
Also, to taste, a little sugar and salt may be added,
I make this in big batches. It saves well.
