Preheat your griddle to 375°F. Add a little oil.
Take each tortilla and drag it across the top of the beef and juices in the crock pot to soak up some of the flavorful fat.
Lay the tortillas on the griddle.
Sprinkle a layer of Chihuahua cheese over each tortilla, then add shredded beef to one side.
Let cook until the cheese is melted, then fold each taco in half.
Continue cooking, flipping occasionally, until the tacos are crispy—about 15–20 minutes total.
