Combine tomatoes, olive oil, garlic, dried oregano, basil, sugar, and salt in a blender and puree until smooth. Alternatively, combine all ingredients in a small sauce pan and use an immersion blender to puree.
Place puree in a small sauce pan, and turn heat to medium-high. Bring to a rolling simmer and allow the mixture to thicken, stirring constantly to prevent burning. About 10 minutes.
Taste for any flavor tweaking: add more salt, oregano, or basil until the taste is just right.
Remove from heat, transfer to a clean mason jar and store until ready to use.
Notes
Keeps in the refrigerator for about a month. If desired, use a pressure canner to preserve the homemade pizza sauce to be used at a later date!
