Get your grill up to temperature. (Our Golden's Cast Iron was approximately 510º when we put our porterhouse on.)
Spray porterhouse and poblano peppers with Duck Fat Spray (or any spray of your choice).
Season porterhouse steak and poblano peppers with Heath Riles BBQ Simple Citrus Rub and Heath Riles BBQ Garlic Jalapeño Rub.
Allow the rub to sweat into the meat while your grill comes up to temperature.
Spray the grates on your grill with Duck Fat Spray or spray of your choice.
Place your porterhouse (or any cut of steak) and poblano peppers on the grill. Cook for 1 and a half minutes and then flip. Cook for another minute and a half and flip again. Continue to flip every minute and a half until an internal temperature of 124º-125º is reached. Once temperature is achieved, remove from the grill.
Allow your steak to rest before cutting into it.
