Instructions

1. Step 1: In a blender, combine 2 chipotle peppers in adobo sauce, 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; blend until smooth to create the marinade.
2. Step 2: Place 1 lb flank steak in a shallow dish and pour the marinade over it, turning to coat evenly. Cover and refrigerate for at least 1 hour or up to 4 hours.
3. Step 3: Meanwhile, prepare pickled red onions by combining 1/2 cup white vinegar, 2 tbsp granulated sugar, and 1/2 cup water in a small saucepan. Heat over medium until sugar dissolves, then pour over 1 medium thinly sliced red onion in a jar. Let sit at room temperature for at least 30 minutes.
4. Step 4: Preheat a grill or grill pan to medium-high heat (about 450°F). Remove steak from marinade and grill for 4-5 minutes per side until medium-rare or desired doneness.
5. Step 5: Transfer steak to a cutting board and let rest for 5 minutes, then slice thinly against the grain.
6. Step 6: Warm 8 small corn tortillas on the grill for 30 seconds each side until pliable and slightly charred.
7. Step 7: Assemble tacos by placing sliced steak on each tortilla, topping with a spoonful of pickled red onions and a sprinkle of 1/4 cup cilantro leaves. Serve immediately.
