Make pork or carne asada recipe as directed. Shred or dice and set aside.
Make cheese sauce and set aside.
For pico de gallo: place all ingredients into a large mixing bowl and toss together. Season with salt and pepper and set aside.
To assemble: Place all the sauces and topping in individual dishes/bowls, creating a buffet-style set up. Have a stack of small plates, next to the big bowl of tortilla chips and cheese sauce followed by the remaining topping ingredients. Serve (for people to build their own nacho creation!).
