I don't know if this is authentic or not, and I haven't tried it yet (but will soon), but it sounds good. When I was in Bolivia they used peanuts in a lot of dishes that we ate, though I never had the chance to eat a chicken dish with peanuts. It says to serve with rice, but I think serving it with any kind of potato dish would be appropriate. Maybe boiled potatoes? We ate a lot of potatoes during our trip, that's for sure!
