Heat oil in a large skillet, preferably cast-iron, over medium-high heat until shimmering. Reduce heat to medium, add steak and cook, turning once, 3 to 5 minutes per side for medium-rare. Let rest on a clean cutting board for 5 minutes.Advertisement
Meanwhile, bring a large pot of water to a boil. Cook rice noodles until just tender, 6 to 8 minutes or according to the package directions. Drain the noodles and rinse under cold water.
Whisk vinegar, fish sauce and sugar to taste in a large bowl until the sugar is dissolved. Slice the steak into thin matchsticks. Add the steak and any accumulated juice to the bowl along with the noodles, cabbage, carrot, radishes, basil and/or mint and peanuts; toss to combine. Serve immediately.
Note: Fish sauce is a pungent Southeast Asian condiment made from salted, fermented fish. Find it in the Asian-food section of large supermarkets and in Asian specialty markets. We use Thai Kitchen fish sauce, lower in sodium than other brands (1,190 mg per tablespoon), in our recipe testing and nutritional analyses.
