In a large pot, start boiling water and chicken broth.
Cut the chicken into small bite-size pieces and add it to the pot. Cook the chicken for 10 minutes.
In a separate pot, bring 3 cups of water to a boil. Rinse and cut the green beans into bite-size as well then add them to the pot. let these simmer on medium-high heat for 10 minutes or just until they are tender. Once they are cooked, drain the water and set them aside.
Back to the broth and chicken pot, the chicken should be cooked after 10 minutes. Season with a teaspoon of minced garlic or garlic powder, Thai chili paste, fish sauce, and sugar. If you want to take it a step further and make it an authentic Thai cuisine soup then consider using fried garlic instead of garlic powder.
Add the rice noodles and cooked green beans to the pot then allow to cook for 2 to 3 more minutes. This will depend on how thick your noodles are. Cook until your noodles are to your desired texture.
Do a taste test and adjust the seasoning according to your preference and serve.
Chop the spring onion and cilantro leaves. slice the lime and garnish your bowl of Sukhothai rice Noodles soup.
