Add the rinsed and drained mung beans, water, sriracha, and maple syrup. Bring to a boil and let simmer over medium heat for about 25-30 minutes, stirring occasionally.
Remove from heat and stir in the soy sauce and tahini. Serve with lime slices and green onions. Drizzle lime juice.
Optional: Pop an immersion blender in there for a more traditionally soft texture.
