Slice sausage and cook in in a large pan on medium-high heat. Add kale and garlic. Cook until softened.
While sausage is cooking, place gnocchi in salted boiling water until they float to the top, 2-3 minutes. Remove from water, toss with olive oil and set aside.
Stir in flour, milk and heavy cream and bring mixture to a simmer. Stir in cheese. Season with salt and pepper to taste. If sauce is too thick, use the pasta water to thin it down.
Cook until sauce has thickened, 2-5 minutes, then fold in gnocchi and toss to coat. Enjoy!
