01 - Preheat your grill to high heat.
02 - In a shallow dish, whisk together olive oil, salt, black pepper, cumin, smoked paprika, minced garlic, and lime juice. Add the flank steak, turning to coat thoroughly. Let marinate at room temperature for 15–20 minutes.
03 - While the steak marinates, place poblano peppers on the grill over direct heat. Turn occasionally until the skin is charred and blistered on all sides, approximately 5–7 minutes. Transfer to a bowl, cover, and let steam for 5 minutes.
04 - Rub off the charred skins from the steamed peppers. Remove stems and seeds, then dice the roasted flesh into small pieces.
05 - In a mixing bowl, combine diced poblano, cherry tomatoes, red onion, jalapeño, cilantro, lime juice, salt, and pepper. Toss gently to combine and set aside.
06 - Remove steak from marinade and place on the hot grill. Cook for 5–6 minutes per side for medium-rare, adjusting time to reach desired doneness.
07 - Transfer the grilled steak to a cutting board and let rest for 5 minutes to allow juices to redistribute. Slice thinly against the grain for maximum tenderness.
08 - Arrange steak slices on plates and top generously with the poblano pico de gallo. Serve immediately.
