This is so easy and cooks as fast as the pasta, I make this when I don't have time to make the "good sauce". It is so versatile I make this in so many ways, I add vodka and/or cream for a quick vodka/pink sauce, add basil, parsley, or red wine, make it your own.
Heat a 2 quart Pot, add the Olive Oil, put the onion in the food processor until you like the texture, my family does not like chunks of onion so I make sure they are processed, add onions to the pot, stir unti translucent
Add the garlic stir for a few seconds, add the can of tomatoes, stir
Once it comes to a boil add the remaining ingredients, stir and simmer for about 30 mins or until the thickness you like, or if in a big hurry add some tomato paste
