Quick Fresh Tomato Sauce

This is a zesty tomato sauce that we prepared so we could then make the Neoclassic Vegetarian Pastitsio. We couldn't find good fresh tomatoes, and so substituted some canned organic diced tomatoes from our local Italian shop. My son prepared the Pastitsio, and wanted his own signature for the sauce (in the spirit of the side bar), and so substituted siracha for the suggested chile pepper. That little bit of zip was a great addition.
