In a large bowl, add in the ground pork, minced garlic, minced ginger, finely chopped lemongrass, fish sauce, sugar, a pinch of salt, and grind of black or white pepper. Mix thoroughly with your hands and then form into meatballs - size them however you like! I like golf ball size.
Place a large pan on medium heat and add in a glug of vegetable oil. Add in the meatballs and fry on each side for 3 minutes until golden.
Next up, add in the thai curry paste and fry for one minute. then add in the chicken stock, and shiitake mushrooms. Bring to a boil, then reduce to a rolling simmer for 10 minutes.
Meanwhile, prepare your vermicelli noodles and beansprouts according to packet instructions. Then drain and set aside.
Once your meatballs are cooked (feel free to slice one in half to ensure it's not raw), taste the broth and season with sugar, salt, pepper, or fish sauce according to your preferences. Divide the noodles, broth, and meatballs between two bowls. Garnish with your toppings and then enjoy!
