Prepare Fried Tortilla Chips.
Spread a third of the chips in a 4-quart baking dish.
Top with a third of the cheese; then add a third of the chiles.
Repeat 2 more times.
Bake in a 400° oven until cheese is melted (about 10 minutes).
Garnish with several spoonfuls of sour cream and olives, if desired.
