In a large pot, heat 1 tablespoon of vegetable oil over medium heat.
Add the chopped onion, minced garlic, and sliced ginger. Sauté until fragrant, about 3-4 minutes.
Add the pork ribs or pork belly pieces and cook until browned on all sides.
Stir in the fish sauce, soy sauce, sugar, turmeric powder, and water.
Bring to a boil, then reduce the heat and simmer for about 45 minutes, or until the pork is tender.
Add the shrimp and cook for an additional 5-7 minutes, or until the shrimp are pink and cooked through.
Season the broth with salt and black pepper to taste. Remove from heat and set aside.
Cook the rice noodles according to the package instructions. Drain and rinse under cold water to stop the cooking process.
In a large bowl, toss the noodles with 2 tablespoons of vegetable oil and 1 teaspoon of turmeric powder until evenly coated.
Divide the turmeric-coated noodles among serving bowls.
Top each bowl with pork pieces, shrimp, and a ladleful of broth.
Add fresh herbs, shredded lettuce leaves, and bean sprouts to each bowl.
Garnish with roasted peanuts, fried shallots, and broken pieces of banh trang.
Enjoy your meal!
