I would roast some and then throw them in the freezer. Once roasted you can soak some whole in soy sauce and they come out great to eat with steak. You can slice them up and fry with onions, garlic, and then add cheese to make chile con queso. Finally lots of different fire roasted salsas can be made with them. My favorite is just a simple pureed jalapeno with salt so you can really enjoy the actual flavor of the chile. You can also blend in a tiny bit of onion or garlic if you like. I avoid adding cumin or oregano but you can try fresh cilantro for a nice fresh taste. Keeping them unroasted, you can also make jalapeno poppers. I believe they still work for poppers even after freezing.
