Substitute for Fire Roasted Chiles?

[dragonbat2006]

I'm in the middle of a Mexican Potato Salad recipe and I realized I misread. (It calls for a can of fire-roasted green chiles and fresh tomatoes. Somehow I read it as a can fire-roasted tomatoes-which I do have!) There is no place I can get to now that stocks canned green chiles, fire-roasted or otherwise. The options I can see are:

1. Leave out the chiles entirely
2. Substitute fresh, BUT my local grocery store stocks Cubanelles, jalapenos, birdseye, Scotch Bonnet, and a bunch of multi-colored long narrow ones it just labels "hot".
3. I have the remains of a can of chipotles in adobo sauce in the freezer
4. My dried spices include Chipotle chile powder, ancho chile powder, crushed red pepper, cayenne, and three kinds of paprika (Spanish, Hungarian, and smoked).

Whatever I pick, I'm not sure about the amount I'd need, either.

Any suggestions?
