How to Make It
Bring the vegetable stock and water to a simmer in a medium saucepan.
Heat 1 tablespoon of oil in large saucepan over moderate heat. Add broccoli rabe and chili flakes and sauté until wilted, about five minutes. Remove from heat and set aside.
In the same pan, sauté 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 stock mixture to 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 add the broccoli rabe, butter, and cheese. Season with salt and pepper and serve.
If eating a gluten-free diet, be sure to use gluten-free stock.
