Combine spinach, ricotta, Parmesan and egg yolks in a food processor. Pulse to combine. Season with salt, pepper and nutmeg. Stir in flour.
Roll small portions of dough into ¾-inch balls (using a small cookie scoop helps) and transfer them to a tray or baking sheet as they are finished. Drop gnudi into boiling salted water and cook until they rise to the top, 3 to 5 minutes.
While gnudi cook, melt butter in a large skillet over medium-high next to pot of water. As gnudi finish cooking, use a slotted spoon transfer them to hot butter in skillet. Add herbs to browning gnudi; cook until gnudi and butter are browned and herbs are crisp, 2 to 3 minutes. Serve browned gnudi with fried herbs and butter.
Before her diagnosis, Caroline wrote a book on cakes called Cake Magic!. She started developing a birthday cake using her gluten-free mix found in that book. Check out other recipes she’s developing for her new life—and the stories behind them—on her blog, The Wright Recipes. Her next book, Soup Club, is a collection of recipes she made for her underground soup club of vegan and grain-free soups she delivers every week to friends throughout Seattle's rainy winter.
