Got this Red Butte Hatch Chile cheese from Beehive Cheese in Utah. Can't remember if I've tried it before or not. Cheddar style, so a much more flavorful cheese than a pepper jack but not super aged - the texture is much more creamy than crumbly. Hatch chile flavor is present but subtle with little heat, though I can't rule out the possibility of a hot bit sneaking in. Will have to try it in a grilled cheese.
It's $9.99 at TJ's. Info from Beehive Cheese's website at this link.
