When I went off to college and had to cook for myself, I made lots and lots of spaghetti with red sauce. One of the few things I knew how to cook, it would feed a crowd, and leftovers went right into the freezer. Maybe there was something meditative about stirring the sauce pot, or maybe I was avoiding doing my homework, or maybe both. All these (many) years later, I prepare spaghetti sauce basically the same way, and this Tex-Mex taco sauce is a peppy riff on that sauce I used to make in my college dorm. You can spice this up or down, by playing with the canned green chiles and chili pepper proportions, but don't leave out all of the hot pepper ingredients. After all, it wouldn't be Tex-Mex without a little something to make you kick up your heels. Cook the full amount of the recipe, and freeze it in smaller portions for tacos, quesadillas, burritos or Sloppy Joes.
