Frontera® Slow Cook Sauce Chipotle Tinga Chicken with Roasted Tomato + Smoky Chipotle. Gourmet Mexican. Perfect for tacos!. Medium. Net Wt 8 oz (225 g). Spicy, smoky tinga sauce combines chipotle chiles with roasted tomato and garlic. I like to slow-cook chicken and potatoes in the sauce to tuck inside tacos or pile onto tortas.
