Instructions

1. Step 1: In a bowl, combine 2 minced chipotle peppers, 3 tbsp fresh lime juice, 2 tbsp olive oil, 3 minced garlic cloves, 1 tsp ground cumin, 1 tsp salt, and 1/2 tsp black pepper to create a marinade. Place 1 lb flank steak into a resealable bag, pour marinade over, seal, and refrigerate for at least 2 hours or overnight for maximum flavor.
2. Step 2: Meanwhile, in a small saucepan, bring 1/2 cup white vinegar, 1/2 cup water, and 1 tbsp sugar to a simmer over medium heat until sugar dissolves. Place 1 medium thinly sliced red onion and 1 thinly sliced jalapeño (optional) into a heatproof jar, pour hot vinegar mixture over, and let cool to room temperature, then refrigerate for at least 30 minutes to pickle.
3. Step 3: Preheat your grill or grill pan to medium-high heat (about 450°F). Remove the steak from marinade and grill for 4-5 minutes per side until medium-rare to medium, with a nice char and juicy interior. Let the steak rest for 5 minutes, then slice thinly against the grain.
4. Step 4: Warm 8 small corn tortillas on the grill for 30 seconds per side until soft and pliable. Assemble tacos by layering sliced steak, a spoonful of pickled onions, and a sprinkle of 1/4 cup chopped fresh cilantro. Serve immediately and enjoy the interplay of smoky, tangy, and fresh flavors.
