Step 1

Marinate the steak: combine all the marinade ingredients and whisk together. Place steak in a zip-top bag and pour the marinade on top. Seal and marinate at room temperature for 30 minutes or in the fridge for up to 8 hours.

Step 2

Make the dressing: Whisk together all the ingredients until the sugar dissolves. Set aside.

Step 3

Cook the rice noodles according to package instructions. Drain and rinse thoroughly with cold water. Transfer them to a large serving bowl.

Step 4

Heat a cast-iron skillet over medium-high heat. Remove the steak from the marinade and shake off any excess. Sear the steak for 3-4 minutes per side, transfer to a cutting board, and rest for 10 minutes. Slice against the grain. Alternately, the steak can be grilled on a hot grill for the same amount of time.

Step 5

Assemble: Arrange the sliced steak on top of the noodles and nestle in the tomatoes and sliced shallots. Drizzle the dressing evenly over everything and top with toasted rice powder and all the fresh herbs. Serve with lime wedges.
