Prepare the grill for two-zone (or direct/indirect cooking). Target 500 degrees Fahrenheit over the direct side of the grill. Coat steaks with olive oil and the beef rub.
Roasted Poblanos Salsa
Grill Poblanos: Place poblano peppers over the direct heat. The peppers will cook quickly. Be sure to stay close to the grill and turn the peppers every 3 minutes so you have a dark char to the skin with some blistering. Remove when all sides are blistered. Place them in a plastic baggie and seal it so they can steam, which makes it easier to remove the skin.
Grill Corn: While the peppers are roasting, grill corn over direct heat. Rotate the corn every 5 minutes so all sides on the husk are charred. Then gently remove the husks to give the corn a little more char and flavor. This will take total of 20 minutes. Now it’s time to make the salsa.
Prep Salsa: Using a sharp knife, remove the kernels from the corn, and remove the skin from the peppers. Dice up the peppers and then combine all remaining ingredients in a large bowl. Season to taste in small increments. More citrus will add acidity, while small increments of salt can minimize any perceived bitter flavor.
Grilled Steak
Grill Over Direct Heat: Place the seasoned steak over direct heat and sear for 3 minutes to get a nice char on the steaks. Flip and continue grilling over direct heat for an additional 3 minutes.
Finish Over Indirect Heat: Move the steak to indirect heat and close the lid. Continue grilling for an additional 6 – 8 minutes or until the internal temperature of the steak reaches 120 degrees F for a rare steak.
Remove and let rest for 10 minutes. Then top the steaks with roasted poblano pepper and corn salsa and serve.
Notes
Variation with Heat: If you want to add some heat and spice to the salsa, roast a jalapeño or a serrano pepper with the poblano, then chop it up to add to the salsa. You only need one for the extra heat.Hint: After the poblano peppers are roasted, place them into a plastic baggie and seal. Let them steam from the heat and then after 15 minutes, remove the peppers. This will allow you to easily remove the skin by peeling, or using a knife to scrape the pepper from the skin.Steak Temperature Guide:
