In a 9-inch cast iron skillet, or similar, add tortilla chips. It doesn't have to be perfect, they can be stacked and scattered. Pour enchilada sauce on top.
2 cups corn tortilla chips, 10 ounce can of medium enchilada sauce
Place over medium-high heat and carefully watch the skillet until mixture comes to a simmer. Reduce heat and then let mixture simmer until tortilla chips have softened, about 7-10 minutes.
Turn on the boiler in your oven.
Add shredded chicken to the top of the tortilla chips then sprinkle cheese all over. Place under boiler for 5 minutes, or until cheese is completely melted. Watch this carefully as the tortilla chips could char and burn.
