Taco Sauce is a rather generic term for a smooth sauce made with tomatoes, chiles and spices. La Victoria has been making a commercially available sauce since 1917. The sauce is used as a condiment on tacos or taco salads.
If you don't have taco sauce you can substitute:
Tomato Puree (Water and Tomato Paste), Red California Chiles, Jalapeños, Onions, Distilled Vinegar, Salt, Modified Food Starch, Garlic and 0.1% Sodium Benzoate (As a Preservative). Gluten Free.
