Preheat oven to 400F and cut 9 tortillas into triangles and place on a baking sheet lined with a wire rack. Lightly spray with cooking spray and sprinkle with salt (optional).
Bake the chips for 8-12 minutes until they begin to slightly brown around the edges and are crispy.
Transfer the chips directly to the baking sheet and remove the wire rack. Sprinkle about 1/3 of the cheese over the chips. Cover with pulled pork and remaining cheese. Bake for 5-10 minutes until the cheese is fully melted.
Drizzle the BBQ sauce and lite ranch over the nachos, top with veggies, and serve.
