In a medium-sized stockpot, bring the broth to a boil over high heat.
Stir in the chicken, aminos, fish sauce, maple syrup, salt, and pepper, then reduce the heat and simmer until the chicken is cooked through, about 10 minutes.
Stir in the noodles and cook until tender, 3-10 minutes depending on the type of noodle and how thick they are. Garnish with green onions to serve.
