1.) Heat the oil in a large skillet over medium/high heat and add in the sausage. Cook until brown and completely cooked through and remove from pan with a slotted spoon.
2.) Add in the brussels sprouts and let them sit for 1-2 minutes before stirring so they start to get crispy. Stir and let them sit again for 1-2 minutes. Then add in the chopped kale, salt and pepper flakes. Reduce heat to medium and cook until kale starts to wilt down.
3.) Add the sausage back in and then make 4 wells in the mixture, crack one egg carefully into each well and cover the skillet with the lid for 5 minutes or until egg reaches your desired consistency.
4.) Top with chives and serve
