01 - Combine soy sauce, olive oil, honey, rice vinegar, garlic, ginger, and black pepper in a bowl. Place flank steak in a shallow dish or zip-top bag, pour marinade over, and refrigerate for at least 30 minutes, up to 4 hours for enhanced flavor.
02 - Remove steak from marinade and pat dry. Heat grill pan or skillet over medium-high heat. Cook steak for 4–5 minutes per side until desired doneness is reached.
03 - Let steak rest for 5 minutes to retain juices, then slice thinly against the grain for maximum tenderness.
04 - Whisk together mayonnaise, Sriracha, and lime juice in a small bowl until smooth and fully combined.
05 - Divide cooked rice among four bowls. Arrange carrots, cucumber, edamame, sliced avocado, and steak slices on top of each portion.
06 - Drizzle with spicy mayo sauce and finish with cilantro, scallions, and sesame seeds. Serve immediately.
