Preheat the oven to 350 degrees.
Use a little bit of melted butter to grease a 9 X 13 glass baking dish.
In a large bowl, beat eggs until light.
Add flour, baking powder, salt, cheese, and melted butter.
Blend together well and then stir in green chiles.
Pour into a well-buttered baking dish and bake for 35 minutes.
Use a toothpick to check if done, so it comes out clean. DO NOT allow it to get dry.
Let cool for a while and then slice into squares and remove with a spatula. Put on a serving plate to serve.
You can store them in the refrigerator and wrap in foil and warm them in a 350-degree oven and serve them if you take them for a dish at a Christmas party, or potluck at work.
Depending on how big you slice the squares, you should be able to get at least 2 dozen squares.
