Get to the Point Execution
Marinate 2 lb flank steak in lime juice, soy sauce, garlic, cumin, and olive oil for 2-4 hours.
Grill flank steak over direct 500°F heat for 4-5 minutes per side to 130°F internal.
Grill sliced bell peppers and onions in a perforated grill basket until charred.
Rest steak 10 minutes and carve thin slices across the grain at a sharp angle.
Step-by-Step Guided Instructions
In a zip-top bag, combine 1/3 cup fresh lime juice, 1/4 cup olive oil, 3 tbsp soy sauce, 4 minced garlic cloves, 1 tbsp ground cumin, 1 tsp chili powder, and 1/4 cup chopped cilantro. Add 2 lbs flank steak and marinate for 2 to 4 hours in the fridge.
Lime juice enzymatically tenderizes the long muscle fibers of flank steak.
Remove steak from marinade and wipe off excess liquid. Place over roaring direct 500°F heat. Grill 4 to 5 minutes on the first side until charred, then flip and grill 4 minutes on the second side.
Flank steak must be cooked hot and fast to medium-rare; cooking past medium turns it tough.
Toss 2 sliced bell peppers and 1 sliced red onion with 1 tbsp oil and 1/2 tsp salt. Grill in a perforated grill basket for 6-8 minutes until blistered and tender.
A grill basket prevents vegetables from slipping through grate openings into the flames.
Rest flank steak on a cutting board for 10 full minutes. Identify the long grain lines. Slice thinly (1/8-inch thick) against the grain with your knife held at a 45-degree angle.
Bias slicing creates wide, melt-in-your-mouth strips with minimal fiber length.
Warm tortillas on the top grill rack for 20 seconds right before serving.
Serve steak strips with mild shredded cheese, sour cream, and salsa in warm tortillas.
