Heat bacon grease or oil in a skillet over medium-high heat. Once heated, arrange shredded pork in an even layer in the pan and cook, uncovered, for 4-5 minutes.
Using tongs, flip the pork. It should appear golden brown and crispy. Continue cooking for another 3-4 minutes.
Remove from heat and serve hot with desired toppings.
Dinner is served! Garnish with desired toppings, like shredded lettuce, diced onion, hot sauce, and cotija cheese.
