1Prep the ingredients: Pluck the mint, basil, coriander leaves from the stalks. Thinly slice the red onion and chillies, then set aside.
2Cook the steak: Sear your steak in a hot pan for 1.5 minutes on each side for a medium-rare cook, but adjust the time for your preferred level of doneness. Let it rest for a few minutes before thinly slicing.
3Make the dressing and toss the salad: In a large bowl, combine the fish sauce, sugar, and lime juice. Add the plucked herbs, sliced red onion, and chillies, then toss well to coat everything in the dressing.
4Assemble the dish: Mix the sliced steak into the salad and let sit for a few minutes to let the flavors combine. Serve over a bed of rice and enjoy!
