After selecting the tomatoes, tear each one lengthwise with your thumb and place in a colander to drain.
Take half of the tomatoes and grind them up in a food mill, food processor or immersion blender. Add the tomato paste and all the other ingredients to this sauce and stir.
Chop the remaining tomatoes into a small, diced slurry. Add this to the other sauce and stir. The sauce should be thick and flavorful.
