A friend, Binh Duong, introduced me to this Vietnamese treat — crunchy noodles topped with fragrant stir-fried beef and vegetables.

The crispy noodles need to be turned over in this recipe. The easiest way to do this is to loosen them on the tray all around the edges, cut into two sections and flip each section with a spatula. If pressed for time, simply serve the beef over boiled angel hair pasta or Chinese noodles.

This dinner takes a few extra minutes to make, but the flavor and texture is worth it.

CRISPY NOODLES

Preheat broiler. Line a baking tray with foil and spray with vegetable oil spray. Bring a large saucepan of water to a boil and add the noodles. As soon as the water returns to a boil, drain and rinse. Shake dry and spread out evenly on baking tray to a rectangle about 10 inches by 6 inches. Spray with vegetable oil spray. Place tray about 10 inches from broiler heat. Keep an eye on them as you prepare the rest of the meal. When the noodles are crisp, after about 5 minutes, remove and flip onto other side. Spray with oil again and return to broiler for another 5 minutes. To serve, cut noodles into 2 portions with a sharp scissors and transfer to individual plates. Makes 2 servings.
