Direction :

1. Preheat the grill to high.
2. Place poblanos, corn and red onions on a large sheetpan. Drizzle lightly with olive oil, and season with salt and pepper. Grill until each vegetable has a nice char. You most likely will need to remove the corn first (you don’t want to over do the corn, and it just needs a little color); the onions should be somewhat soft and charred as well; the poblanos need the most time on the grill and should be charred all around — don’t be impatient here.
3. Transfer poblanos to a small bowl and cover with plastic wrap or a plate to create as much of an airtight seal as possible. Meanwhile, chop the red onions and add to a large mixing bowl. Remove the corn from the cob using a sharp knife and add to bowl. Chop the scallions finely and add to bowl. Season with 1/2 teaspoon kosher salt, 2 tablespoons olive oil, and the juice of one lime. Add hot sauce or red pepper flakes to taste.
4. When poblanos have cooled completely or when they are cool enough to handle, massage the skins off, and remove seeds and stem — this is kind of a pain, but just push through it. Give them a nice chop and add to the bowl. Chop up cilantro to taste and add to bowl. Give it a stir. Taste and adjust seasoning as necessary. I added 1/4 teaspoon of sugar, the juice of another lime, and a pinch more salt.
5. If grilling steaks for tacos, preheat the grill to high, season steak with salt and pepper and grill to desired doneness — 5 minutes total for a 1-inch New York Strip produced a nice medium rare steak. Let rest 10 minutes before slicing.
6. While the steaks are resting, turn off the grill, throw the tortillas on the grates, grill on one side only until warm and marked with grill lines. Wrap in foil to keep warm.
