My Dad used to make a similar recipe. I haven't tried this version.

Ingredients
1 large can whole ortega chilies
1 pound Jack Cheese, grated
1 pound Cheddar cheese, grated
4 eggs
2 teaspoons flour
2 small cans evaporated milk
2 small cans tomato sauce
Method
Split chilies, de-seed an d wash. In a greased 9 x 13 inch pan, arrange chilies and cover with Cheddar cheese. Beat together: milk, eggs and flour. Pour mixture over the chiles and cheese. Bake at 400 degrees for 30 min. Remove from oven and place Jack cheese on top then cover with tomato sauce (also sliced olives and chopped green onion if desired). Return to oven for about 10 min. Or until cheese melts. Let set 5 min. Before serving.
