Ingredients

Instructions

  1. Step 1: In a bowl, whisk together 2 tbsp olive oil, 1 tsp ground cumin, 1 tsp smoked paprika, 1 tsp chili powder, 1/2 tsp garlic powder, 2 tbsp lime juice, 1 tsp salt, and 1/2 tsp black pepper. Add 1 lb flank steak and coat evenly. Marinate for at least 30 minutes.
  2. Step 2: Preheat grill to medium-high heat. Grill 1 medium sliced white onion rings brushed with 1 tbsp olive oil directly on the grill grates, turning occasionally, until charred and softened, about 8 minutes.
  3. Step 3: Grill the marinated flank steak for 4-5 minutes per side for medium-rare, or longer to desired doneness. Let rest 5 minutes, then slice thinly against the grain.
  4. Step 4: Warm 8 small corn tortillas on the grill for 30 seconds per side. Assemble tacos by layering sliced steak, charred onion rings, 1 small diced jalapeño, and 1/4 cup chopped fresh cilantro on each tortilla before serving.
