01 - Combine ground pork, shrimp, glass noodles, wood ear mushrooms, carrot, garlic, green onions, egg, fish sauce, and black pepper in a large bowl. Mix thoroughly until all ingredients are evenly distributed.
02 - Fill a large shallow dish with warm water. Quickly dip each rice paper wrapper for approximately 5 seconds until pliable, then transfer to a damp cloth to prevent drying.
03 - Place 2 tablespoons of filling near the bottom third of each wrapper. Fold the sides inward, then roll tightly from bottom to top to create a secure cylinder. Repeat until all filling is used.
04 - Heat 2-3 inches of vegetable oil in a deep pan to 340°F. Fry spring rolls in batches for 5-7 minutes, turning occasionally until golden brown and crispy. Drain on paper towels to remove excess oil.
05 - Cook rice vermicelli noodles according to package directions. Rinse thoroughly under cold running water to stop cooking and prevent sticking. Drain well.
06 - Dissolve sugar in warm water. Add fish sauce, lime juice, minced garlic, sliced chili, and shredded carrot if desired. Whisk until sugar is completely dissolved and ingredients are well combined.
07 - Divide cooked noodles evenly among 4 serving bowls. Arrange lettuce, cucumber, bean sprouts, and fresh herbs on top. Slice each spring roll diagonally into pieces and place 3 rolls per bowl. Garnish with chopped roasted peanuts.
08 - Serve immediately with nuoc cham sauce on the side for dipping, or drizzle sauce directly over the bowl according to preference.
