Preheat the oven to 400 degrees F.
Line a large baking sheet with tortilla chips, mostly in one layer. It is ok if some overlap.
Cover the chips with 1 cup of cheese. Add the chicken, beans, and green chiles. Cover with the remaining 1 cup of cheese.
Place the pan in the oven and cook until the cheese is melted, about 5 to 7 minutes.
Remove the pan from the oven and top with avocado, scallions, cilantro, jalapeño pepper, and sour cream. Spoon salsa verde over the top of the nachos or serve the salsa on the side. Serve immediately.
