Preheat smoker to 350-400 degrees. Spray the baking sheet or cast iron skillet with a cooking spray, and add a layer of tortilla chips.
Add 3/4 of the shredded cheese, and spread evenly over the chips.
Add a few spoonfuls of the queso sauce evenly over the chips.
Spread the meat evenly over the chips, cheese, and queso sauce. Top with remaining shredded cheese.
You can add the beans and corn at this point, or add them after the nachos have cooked. If you do that, then you should heat the corn and beans separately.
Add the nachos to the smoker and cook, with the lid down, for 10-15 minutes, or until the cheese is completely melted.
Remove from the smoker and add a drizzle of sour cream and add the pico de gallo and cilantro.
Serve on individual plates with additional sour cream, pico de gallo, and salsa roja.
Notes
For additional people, double the quantities of chips and cheese. You can also do a second layer of each ingredient.
