01 - Combine ground pork, shrimp, soaked glass noodles, wood ear mushrooms, grated carrot, minced garlic, chopped 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. Briefly dip each rice paper wrapper for approximately 5 seconds until pliable, then transfer to a damp cloth to prevent drying out. Work quickly to maintain wrapper flexibility.
03 - Place 2 tablespoons of filling near the bottom third of each softened wrapper. Fold both sides inward toward the center, then roll tightly from bottom to top, ensuring the filling is completely enclosed. Repeat until all filling and wrappers are used.
04 - Heat 2-3 inches of vegetable oil in a deep pan to 340°F. Carefully add spring rolls in batches, frying for 5-7 minutes while turning occasionally. Cook until golden brown and crispy throughout. Remove and drain on paper towels to absorb excess oil.
05 - Cook rice vermicelli noodles according to package directions, typically boiling for 3-5 minutes until tender. Drain thoroughly and rinse under cold running water to halt cooking and prevent sticking. Shake off excess water well.
06 - Dissolve sugar in warm water, then incorporate fish sauce, lime juice, minced garlic, sliced red chili, and shredded carrot. Whisk vigorously until sugar is completely dissolved and ingredients are emulsified. Adjust seasoning to taste.
07 - Divide prepared rice vermicelli among 4 individual serving bowls. Arrange shredded lettuce, julienned cucumber, bean sprouts, and fresh herbs on top of the noodles. Slice each fried spring roll diagonally into 3-4 pieces and distribute evenly among bowls. Garnish with chopped roasted peanuts.
08 - Serve immediately with nuoc cham dipping sauce on the side. Guests can either drizzle sauce over their bowl or dip spring rolls directly. For optimal texture, consume while spring rolls remain crispy.
