Place flank steak in a deep container or reusable silicone bag and let come to room temperature.
In a small bowl combine olive oil, lime juice, soy sauce, sesame oil and garlic. Whisk to combine.
Pour marinade over the steak and ensure it is fully covered. Let marinate a minimum of 30 minutes.
Ensure grill has clean grates and bring to medium/high heat (450-500 degrees F).
Remove steaks from marinade (let any excess marinade fall off) and place over direct heat. Close grill.
Sear on grill 3-5 minutes per side for medium rare or until the center of the thickest part of the steak reaches 130 degrees F using an internal meat thermometer.
Remove from grill and let rest for 10 minutes.
Cut into strips (cut against the grain).
Divide steak and other salad ingredients between bowls.
