Melt butter in a large saucepan over medium high heat.
Add green beans, onions, and garlic.
Stir in soy sauce.
While stirring, add bouillon and water.
Reduce heat to low and simmer, stirring occasionally, for 20 minutes or until beans reach desired tenderness.
CAUTION: THIS CAN GET SALTY! If you don't like salty food, use low sodium soy sauce and cut WAAAY back on the bouillon until you get it to your preference. My in-laws are on a low-sodium diet, and they don't like it, but my family can't get enough. Go figure! :).
