dice onions, a carrot, and celery saute in olive oil add some garlic salt and pepper start adding a good red wine (not cooking wine, blech, they add salt to it so drunken chefs won't steal it) add a can of tomatoes, diced, or stewed. add some sugar (just whatever you can pinch between your fingers) (if it's too runny, just let it simmer, it'll thicken.... or add a tablespoon of tomato paste and let it simmer) then add some dried herbs, oregano, basil, a bay leaf if you must (but don't eat it). add more wine, and let it simmer down keep tasting it, when it makes the sides of your mouth tingle with delight it's ready if it doesn't add more wine, and reduce.
throw it together with some pasta and drink some wine
adjust the vegetables and stuff to your liking the important things are tomatoes, sugar and wine. The sugar cuts the acidity of the tomatoes.
