Step 1 Place noodles in a large heatproof bowl and pour steaming hot water over the noodles. Separate the noodles by pulling them apart with forks and let it rest 5-7 minutes to soften until tender. Rinse with cold water to cool them down then drain really well. Chop the rice noodles to about 1-inch pieces on a cutting board and transfer to a large mixing bowl.
Step 2 Place a deep skillet over medium/high heat. Add 1 Tbsp oil and saute ground pork until cooked through and season with 1/2 tsp salt. Transfer to the mixing bowl with noodles.
Step 3 In the same skillet, add 2 Tbsp oil, sliced mushrooms, diced onions, and shredded carrots. Saute until softened (5-6 minutes) then add 4 cups cabbage and saute just until wilted (2 minutes). Season with 1/2 tsp salt and transfer to the mixing bowl with the noodles.
Step 4 Season egg roll mixture with 1 tsp salt, 1/2 tsp black pepper, 1 1/2 Tbsp soy sauce, and 1 tsp sesame oil. Since the filling is fully cooked, taste it, and add more seasoning to taste. Drain any excess liquid from the filling if present.
Step 5 Peel back 1 egg roll wrapper and place it in a diamond shape on a clean work surface. Keep remaining egg roll wrappers covered with a damp paper towel to keep them from drying out. Add 1/4 cup of filling onto the bottom third of the wrapper.
Step 6 Fold the bottom corner over the filling and tuck underneath. Roll tightly towards the center then fold in the sides, roll again then brush the last flap lightly with beaten egg and roll to seal. Repeat with remaining egg rolls. Keep the formed egg rolls covered with plastic wrap so they don’t dry out.
Step 7 Heat oil in a dutch oven or fryer to 350˚F. Fry 5-7 egg rolls at a time for 5-6 minutes or until golden brown and crispy. Egg rolls should sizzle when they are in the oil. Keep the temperature of the oil between 340-350˚F while frying. Transfer to a wire rack and cool 15 minutes before serving with your favorite sauce.
