2. Prepare the carnitas according to package instructions; set aside.
3. Arrange a single layer of tortilla chips on a large rimmed baking sheet (I used a jelly roll pan.) Top with 1/3 of the cheese, then add a second layer of chips and top with the remaining cheese.
4. Spread the carnitas evenly over the chips. Bake at 400° for 8-12 minutes, until cheese is completely melted.
5. Remove from oven; top with queso fresco, red onion, jalapeños, cilantro, and guacamole OR any toppings of your choice. Serve immediately.
