How to Make It
Bring the vegetable stock and water to a simmer in a medium saucepan.
In a large saucepan, sauté the pancetta over moderate heat until browned, about 5 minutes. Add radicchio and sauté for 1 minute. Remove pancetta and radicchio from pan and set aside.
In same pan, sauté the onion and garlic over moderate heat until softened, about 5 minutes. Add the millet and cook, stirring, for 2 minutes. Add the wine and cook 1 minute.
Add the stock mixture to the millet 1 cup at a time, stirring occasionally, and adding more stock once it has been absorbed, about 30 minutes total. Once the millet is al dente, remove from the heat and stir in the pancetta, radicchio, butter, and cheese. Season with salt and pepper and serve.
