1 (8 ounce) can of tomato sauce
1/3 cup water
¼ teaspoon chili powder
1½ teaspoon ground cumin
1½ teaspoons dry onion flakes
1 tablespoon white vinegar
½ teaspoon garlic powder
½ teaspoon garlic salt
¼ teaspoon paprika
¼ teaspoon white sugar
¼ teaspoon cayenne pepper
Mix everything and simmer (on very low) for 15-20 minutes. Serve hot. The "spice level" is very moderate if you use it right away. It is a little spicier if you let it sit in the fridge overnight.
Serve (as a hot condiment) with any Mexican food.
NOTE: I was surprised to see that there is vinegar in this sauce (you can't taste it in the final product).
NOTE: I don't usually buy garlic salt. I just mix it up with 3 parts salt to 1 part garlic powder, stir well.
