Cook the brussel sprouts using your favorite method. I just boiled them for about 12 minutes in salt water. Rinse and cut the sprouts in two.
Melt the butter in a skillet on medium heat. Add the bacon and cook, stirring occasionally for about 5 minutes. Add the brussel sprouts and chestnuts and continue cooking until the bacon is cooked through and the sprouts are slightly browned.
