In a stockpot or Dutch oven, combine the hash browns and chicken broth. Bring to a boil, then turn heat to medium-low, and simmer for about 10 minutes.
In a separate bowl, stir together the gravy mix and water. Stir the gravy mixture into the potatoes, and allow to simmer until thickened. Remove from heat and let stand for a few minutes before serving.
Serve hot topped with chopped green onions and grated cheese.
