Preheat the oven to 350 degrees F. Cut each tortilla into 8 wedges.
In a small bowl, combine the olive oil, garlic powder, and onion powder. Brush over the tortilla wedges. Arrange the tortilla wedges between 2 baking sheets, so they are in a single layer. Sprinkle lightly with salt.
Bake for 10 minutes until the edges are golden and crispy. Remove from the oven.
Add the shredded chicken to a medium mixing bowl. Pour in the wing sauce and stir until evenly coated. Set aside.
Using one of the baking sheets, arrange ½ of the chips into a foundation layer for the nachos. Top the chips with ½ of the chicken mixture, 2 tablespoons of blue cheese crumbles, and then the 1 cup of shredded Monterey Jack cheese, spreading them evenly over the chips. Repeat the layers, but swap in the blue cheese dressing for the crumbles.
Bake for 8-10 minutes until the cheese is melted.
Remove from the oven. I like to drizzle a little extra blue cheese dressing and wing sauce over the top, too. Then garnish with chives, celery, and the remaining blue cheese crumbles. Serve warm.
