01 - Combine beef slices with olive oil, soy sauce, black pepper, and minced garlic in a medium bowl. Toss to coat evenly and marinate for 10 minutes.

04 - Whisk together extra virgin olive oil, balsamic vinegar, Dijon mustard, honey, salt, and pepper until emulsified.
05 - Slice the cooked beef into bite-sized strips and layer on top of the salad base.
06 - Drizzle the dressing over the salad, then sprinkle with toasted sesame seeds and crumbled feta cheese if desired.
07 - Serve immediately to preserve freshness and texture.
