Boil 2 cups of water, I heat the water in the microwave for 4 minutes. Cut dried chiles in half, remove stem and seeds. Then chop the dried chiles into pieces and set in hot water for 10 minutes. Drain water from the chiles and set the chiles aside.In a blender add tomato sauce, chicken broth, chiles that have been soaked, Mexican oregano, diced green chiles, cumin, coriander, garlic cloves and salt and blend on high for 3 minutes or until sauce is smooth and there are no chunks.*Just make sure you have a good processor or a blender, so you don’t end up with any large chile flakes.Serve as a salsa our favorite way to eat this sauce, or dress on burritos or enchiladas.
