Creamy Gnocchi and Sausage Skillet

Heat olive oil in a large skillet over medium-high heat. Add sausage and cook for 5 minutes. Add mushrooms and onion; cook until soft, about 4 minutes. Add garlic and cook until fragrant, about 1 minute.

Stir in wine and Dijon mustard. Add gnocchi and half-and-half; bring to a simmer. Reduce heat to medium, cover, and cook for 5 minutes. Remove the lid and stir in spinach and Parmesan cheese. Cook until sauce has thickened and cheese has melted, about 1 minute.

Divide mixture between 4 serving plates and top with crushed chili flakes.
