One trick I use to make taco meat extra tasty is to follow the directions of the taco seasoning packet, but then when I add the seasoning, I also take a can of chipotle peppers, chop them up, and add them to the beef along with the seasoning. I also use pan fried corn tortillas for the shells. All of this goes well with margaritas, maybe one day I will learn how to make those from scratch.
