Heat a large saucepan over medium-high heat. Coat pan with cooking spray. Add onion to pan; sauté 3 minutes or until tender. Add garlic to pan; sauté 30 seconds. Stir in wine; cook 30 seconds.
Add tomato paste, oregano, pepper, and tomatoes. Reduce heat, and simmer for 20 minutes or until thick.
Remove sauce from heat; stir in basil and vinegar. Cool.
Notes
This sauce is a chunky tomato sauce. If you prefer a smoother pizza sauce, toss it in a food processor or blender with about 1 tablespoon water and blend until smooth.
This sauce can be prepared ahead of time- up to one day. It freezes well, too, for up to one month.
