Add chicken sausage with ½ tablespoon oil to a large non-stick skillet on medium-high, cook until browned on both sides. Remove from pan and set aside.
Add cauliflower gnocchi to the pan with the remaining oil. Let cook in oil without touch for 5-10 minutes, until gnocchi starts to brown on the side down. Individually turn over with tongs and brown/crisp on the other side.
Add half and half to the pan and cook until thickened, about 3-5 minutes. Add chicken sausage to the pan, followed by the parmesan cheese. Mix well to combine and then stir in the spinach until wilted.
