2 pounds flank steak trimmed of excess fat
1 recipe Mojo sauce (recipe below)
Olive oil for coating grill
Kosher salt and freshly ground pepper
16 corn tortillas
2 limes for serving
- 4 garlic cloves, minced
- 1 jalapeno, minced
- 1 large handful fresh cilantro leaves, finely chopped
- Kosher salt and freshly ground black pepper
- 2 limes, juiced
- 1 orange, juiced
- 2 tablespoons white vinegar
- 1/2 cup olive oil
Lay the flank steak in a large zip-lock bag and pour the mojo over it. Refrigerate for 1 hour or up to 8 hours, so the flavors can sink into the meat. Don't marinate the steak for more than 8 hours though, or the fibers break down too much and the meat gets mushy.
Preheat an outdoor grill or a ridged grill pan (I used our George Foreman) over medium-high flame (you can also use a broiler). Brush the grates with a little oil to prevent the meat from sticking. Pull the steak out of the mojo marinade and season the steak on both sides with salt and pepper. Grill (or broil) the steak for 7 to 10 minutes per side, turning once, until medium-rare. Remove the steak to a cutting board and let it rest for 5 minutes to allow the juices to settle. Thinly slice the steak across the grain on a diagonal.
Warm the tortillas for 30 seconds on each side in a dry skillet or on the grill, until toasty and pliable.
To make the tacos, stack up 2 of the warm tortillas, lay about 4 ounces of beef down the center, and sprinkle with sweet onion and cilantro mixture.
