01 - Combine ground pork, chopped shrimp, soaked glass noodles, wood ear mushrooms, grated carrot, minced garlic, green onions, egg, fish sauce, and black pepper in a large mixing bowl. Mix thoroughly until all ingredients are evenly distributed and the mixture becomes cohesive.
02 - Fill a large shallow dish with warm water. Quickly dip each rice paper wrapper for approximately 5 seconds to soften, then transfer to a damp kitchen towel. Work with one wrapper at a time to prevent drying out.
03 - Place approximately 2 tablespoons of filling on the bottom third of each softened wrapper. Fold the sides inward toward the center, then roll tightly from bottom to top, ensuring the filling is completely enclosed. Repeat with remaining wrappers and filling.
04 - Heat 1 inch of vegetable oil in a deep pan to 340°F. Fry spring rolls in batches of 4-5 for 5-7 minutes, turning occasionally, until golden brown and crispy throughout. Transfer to paper towels to drain excess oil.
05 - Cook rice vermicelli according to package instructions, typically boiling for 3-5 minutes until tender. Drain immediately and rinse thoroughly under cold running water to stop cooking and prevent sticking. Drain well.
06 - Dissolve sugar in warm water. Add fish sauce, fresh lime juice, minced garlic, sliced red chili, and shredded carrot. Whisk vigorously until sugar is completely dissolved and ingredients are fully incorporated.
07 - Divide cooked noodles evenly among 4 serving bowls. Arrange shredded lettuce, julienned cucumber, bean sprouts, and fresh herbs on top. Slice each spring roll diagonally into 3 pieces and place 3 spring rolls per bowl. Garnish with chopped roasted peanuts.
08 - Serve immediately with nuoc cham sauce on the side for dipping, or drizzle directly over the bowl according to preference. Extra herbs and lime wedges may be offered on the side.
