Spaghetti Sauce

This sauce is so simple to make and it's really good. It's so much better than jarred sauce. Makes 6 servings.

1 (28 ounce) can crushed tomatoes
2 (8 ounce) cans tomato sauce
1 (6 ounce) can tomato paste
3 cloves garlic, minced
1 tablespoon white sugar
2 tablespoons red wine vinegar
2 teaspoons dried oregano
1 pinch crushed red pepper flakes

In a large skillet combine the crushed tomatoes, tomato paste, tomato sauce, garlic, sugar, vinegar, oregano and red pepper flakes. Stir all together and simmer over low heat for at least 30 minutes (for the best flavor). Stir frequently to prevent burning.
