Heat the oil in a large pan over medium heat. Add the onion and garlic and cook, stirring frequently, for about 5 minutes, until soft and translucent. Do not brown; reduce the heat if necessary.

Add the tomato sauce, chipotle peppers and sauce, sugar, cumin, oregano, and salt. Bring to a gentle boil, then reduce the heat to low and simmer, uncovered, for about 10 minutes. Stir in the chicken and cilantro.

Preheat the oven to 425 degrees F and set 2 racks in the center of the oven.

Arrange the tortilla chips in a single layer, overlapping slightly, on two 13×18-inch baking sheets. Spread the chicken evenly over the chips, followed by the cheeses.

Bake for 5 to 8 minutes, until the cheese is melted. Remove the nachos from the oven, then sprinkle with scallions and cilantro.

Serve immediately, passing the guacamole, sour cream, and lime wedges separately, and enjoy!
