Chop off both tips of the green beans then slice into two. Put aside.
Chop the sausage links into bite-sized chunks as well. Reserve in a bowl. For easy chopping, refrigerate the sausage for around 15 minutes before cutting.
Preheat a skillet then pour the oil into heat. Sear the sausage chunks for 5 minutes.
Once brown, toss in the onion and chopped green beans. Sauté for 4-5 minutes more.
Gently pour in the cream. Season with pepper and salt. Fold the mix with a spatula to incorporate all the ingredients together. Leave for an additional 3 minutes before turning off the heat.
