Fry tortillas in oil and dip into heated chile sauce.
Place one tortilla in a small, shallow, ungreased baking dish; spoon over surface about 2 tablespoons shredded Cheddar, about 2 tablespoons chopped green onion, and a little of the chile sauce.
Add remaining tortillas, preparing each layer the same way.
Pour remaining sauce over stack, and top with remaining cheese.
Bake, uncovered, in a 350° oven for 15 to 20 minutes or until hot.
