Heat hard taco shells in the oven to make them crisp, or warm corn or flour tortillas in the microwave for soft tacos. Spoon the meat into the shells, then add your favorite toppings (lettuce, tomato, cheese, sour cream, taco sauce, etc)
This makes just shy of 3 pounds of meat, which is a hell of a lot of tacos. Any leftover meat you can put in the fridge and reheat in the microwave for nachos later. Or more tacos.
