Carne Asada with Grilled Onions

Step 1

In a shallow dish, whisk together the lime juice, garlic, half the cilantro, salt, pepper, and olive oil.

Step 2

Add the flank steak, turning to coat, and marinate in the refrigerator for at least 30 minutes or up to 4 hours.

Step 3

Preheat a grill or grill pan over high heat.

Step 4

Brush the onion rounds lightly with oil and grill for 3-4 minutes per side, until charred and tender.

Step 5

Remove the steak from the marinade and grill for 4-5 minutes per side for medium-rare, or until it reaches your desired doneness.

Step 6

Let the steak rest for 5 minutes, then slice thinly against the grain.

Step 7

Warm the corn tortillas on the grill for 30 seconds per side.

Step 8

Serve the sliced steak and grilled onions in the tortillas, topped with the remaining cilantro.
