Bring the water to a boil, then stir in the Better Than Bouillon, fish sauce, hoisin, sugar, ginger, and green onions. Lower the heat to a simmer and simmer for 15 minutes.
Strain the soup into another deep pot, discarding the solids. Place the broth back into the original pot, stir in the turkey, and keep on low heat.
Meanwhile, cook the noodles. Bring another pot of water to boil and cook the rice noodles according to package directions. Give them a couple stirs while they boil as rice noodles tend to stick together.
Divide the noodles evenly among four bowls. Ladle the broth over top. Serve with generous portions of fresh herbs, limes, jalapeno slices, bean sprouts, and Sriracha, letting everyone customize their bowls to their liking.
