Fry the bacon until almost crisp; remove from skillet and drain all but a couple of tablespoons bacon grease. Crumble the bacon and set aside.

Add onion to skillet. Saute for a few minutes. Pour in hominy and stir until warmed. Add cheese, chilies, jalapenos (if using), and bacon and stir until cheese is melted. Remove from heat. (It is a bit less messy if you wait to add cheese until stirring into the baking pan.)

Pour mixture into a large baking pan and sprinkle with a little more cheese, bacon, and green chiles, if desired. (Really, you just gotta add these!)

Bake at 350 for 15 minutes, or until heated through and cheese on top is nicely browned.
