Preheat oven to 350F. Place parchment paper in a broiler pan and layer on nachos, chicken, tomatoes, jalapenos, green onion, and lastly the cheeses.
Use your discretion on the amount you would like. Sprinkle with the smoked paprika.
Bake for 10 minutes and then finish off under the broiler to brown slightly, about 2 minutes. Using the parchment paper, transfer nachos onto a serving platter.
