Heat the oil in a large skillet over medium-high heat. Add in the brussels sprouts and cook for around 2-3 minutes. Add in the salt, pepper and red pepper flakes. Cook for an additional 3 minutes. Transfer to a plate and set aside.
In the same skillet, melt the butter. Add in the gnocchi and cook until they begin to brown, around 2-4 minutes.
Mix in the brussels sprouts. Stir in the Parmesan and enjoy!
