Step 1

Season steak with 1/4 teaspoon each pepper and salt. Heat oil in a large cast-iron skillet over medium-high heat. Add the steak and cook, undisturbed, until slightly charred, 3 to 4 minutes. Turn and continue to cook, adjusting the heat as necessary, until an instant-read thermometer inserted in the thickest part registers 120 degrees F for medium-rare, 3 to 4 minutes more. Transfer to a plate and let rest for 10 minutes.

Step 2

Meanwhile, combine strawberries, lime zest and juice, vinegar, honey and the remaining 1/2 teaspoon pepper and 1/4 teaspoon salt in a medium bowl. Let stand at room temperature for 10 minutes.

Step 3

Thinly slice the steak against the grain. Stir shallot, mint and cilantro into the strawberry salsa. Divide the steak and salsa among tortillas. Serve with lime wedges and more cilantro, if desired.
