In this vegetarian Vietnamese appetizer, cellophane noodles, fried tofu, sauteed shallots, crunchy lettuce, carrots, and jicama are topped by a sprinkling of herbs and rolled in diaphanous rice paper rounds.
Make the filling: Soak bean threads in hot water for 20 minutes. Drain, and rinse in cold water. Cut into 2-inch lengths.
Heat 2 tablespoons oil in a large skillet over medium heat. Add shallots; cook, stirring occasionally, until golden brown, about 5 minutes. Using a slotted spoon, transfer to a small bowl; set aside.
Add tofu to skillet; cook, stirring, 3 minutes. Add 1 tablespoon soy sauce; cook 1 minute more. Transfer to a large bowl.
Add remaining 2 tablespoons oil to skillet; heat until hot but not smoking. Add jicama and carrots; cook, stirring occasionally, 3 minutes. Add bean threads and remaining 3 tablespoons soy sauce; cook, stirring occasionally, 2 minutes. Season with salt and pepper. Transfer to bowl with tofu; stir to combine.
To assemble each roll, soak a wrapper in a bowl of warm water until softened, about 30 seconds. Transfer to a work surface. Lay 1 or 2 lettuce leaves lengthwise at 1 end of wrapper. Spread 1/2 cup tofu mixture over lettuce; sprinkle with shallots. Top with basil and cilantro. Fold ends in and roll tightly to enclose filling. Cover with a damp cloth until ready to serve. Halve rolls. Serve with dipping sauce.
