I decided to just cut them up and freeze them because I didn't have time to do anything else after getting home from our trip. I ended up with 6 big freezer bags full plus some to stick in the fridge. I think I will be good for a long while.
With the fresh ones I made stuffed peppers from this recipe. They turned out really good! Some of the chiles were a bit hotter than others, but they all got eaten.
