Dice up onions. Heat olive oil in a pan then saute the diced onion on high heat until it gets a glassy / translucent look for about 3-5 minutes. Add the crushed garlic and saute until it gets fragrant for about a minute. Mix in the tomatoes or the pureed tomato. Spoon in the vinegar and/or the optional white wine. Cook it on low heat for about 5 - 10 minutes or until the sauce gets the desired thickness. Sprinkle in the paprika and any other optional flavorings then cook it for another minute. Pour the sauce into a high walled bowl then blend everything together until getting an orange looking sauce.
