Kristin used Anaheim's, but any type will work, I guess depending on size. If a dog will fit in a pablano I think it will have great flavor, they are great for relleno, why not this? The Anaheim was a good size for the length of the dog. I just put that cooking rack over the gas range and turned when they got charred. I think your flat top is really going to do a job on the cooking portion of the cook!
