Although sirloin works fine in this salad, you could, for special occasions, spring for tender, deeply flavorful (but more expensive) rib-eye. You can also make the whole thing ahead of time, as long as the dressing is added right before serving.
Put cilantro, sprouts, cucumber, onion, and celery in a large bowl. In a small bowl, mix together fish sauce, chili sauce, and lime juice to make dressing. Set both aside.
Heat oil in a large frying pan over high heat. Add beef and cook, stirring occasionally, until no longer pink, about 4 minutes. Drizzle beef with soy sauce. Add beef to vegetable mixture, pour dressing over salad, and toss gently to combine.
