How to Make It
Marinate the steak in soy sauce for 30 minutes.
Cook the steak in 2 teaspoons of the olive oil in a large skillet over medium-high heat, 3 to 5 minutes per side for medium-rare. Let rest 5 minutes, then slice against the grain.
Toss the steak with the romaine, cilantro, queso fresco, onion, avocado, 3 tablespoons of the olive oil, and lime juice; season with ½ teaspoon salt.
