Slice the meat. To be able to slice the steak as thin as we need to, it helps to partially freeze it first (about 1 hour to 1 1/2 hours). After that, thinly slice the steak across the grain. Around 2mm-thick slices is perfect.
Marinate. Stir together all the marinade ingredients in a large bowl. Add the steak and stir gently to coat. Cover the bowl with plastic wrap and refrigerate at least 4 hours, or up to 8 hours.
Cook the meat. Working in batches, sear the meat in a large cast-iron or other heavy skillet over high heat.
Cook the veggies. Once all the meat is cooked, turn the heat down to medium. Add the onion, carrot, and half of the scallion. Cook until the vegetables are caramelized and starting to soften, about 1 minute, flipping them constantly.
