lightly coat the chicken with flour.
In a large saucepan over medium heat, melt the butter and saute the
chicken pieces for 3 to 5 minutes, until golden on all sides. Season with salt,
pepper, and garlic powder.
When the chicken pieces turn a golden color, add the onions, saute for 2 or
3 minutes, and immediately add the wine.
Reduce the heat, cover, and simmer for about 40 minutes, until chicken
is tender and done and onions are translucent and soft. Transfer to a serving
bowl, and serve immediately.
