Add the chicken, green onions, 2 teaspoons soy sauce, 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 until cooked through. Transfer to a plate.To the same pot, add 3 tablespoon oil, the shallots, ginger, and garlic. Cook until fragrant, about 2 minutes. Add the butternut squash and curry paste. Cook another 5 minutes, stirring occasionally. Stir in the coconut milk, broth, 1/4 cup soy sauce, fish sauce, and peanut butter. Slide the meatballs back into the curry. Simmer over medium heat until the meatballs are cooked through, 5-8 minutes. Stir in the spinach. Meanwhile, cook noodles according to package directions.Divide the noodles between bowls and ladle the curry over. Top each bowl with pomegranate, cilantro, and green onions.
