Add the chicken, green onions, ginger, garlic, and a pinch of pepper to a bowl. Mix until just combined. Coat your hands with a bit of oil, and roll the meat into tablespoon-size balls (will make 15-20 meatballs).Heat a large pot over medium-high heat and add 2 tablespoons oil. When the oil shimmers, add the meatballs and sear until crisp, about 4-5 minutes, turning them 2-3 times. Toss in the bok choy and cook 2 minutes more, until just charred on the edges. Transfer everything to a plate.To the same pot, add the remaining 1 tablespoon oil, and the curry paste. Cook until fragrant, about 2 minutes. Stir in the coconut milk, chicken broth, fish sauce, and honey. Slide the meatballs and bok choy back into the soup. Simmer over medium heat until the meatballs are cooked through, 5-8 minutes. Stir in the herbs. Meanwhile, cook noodles according to package directions.Divide the noodles between bowls and ladle the soup over. Top each bowl as desired with basil, green onions, shallots, lime juice, and chili oil.
