Prep all ingredients, including finely mincing the garlic cloves. In a saucepan on medium-low heat, add olive oil, salt, red pepper flakes and garlic. Cook gently for about 5 minutes or until garlic has softened. Do not allow garlic or pepper to burn! Add the can of tomatoes and stir well. Cook uncovered for 15 minutes, stirring regularly. (If I have time, I cook mine for at least 30 minutes or more to develop the flavor.) Serve with pasta, use as a pizza or dipping sauce, or freeze for later use.
