Lemony Braised Greens with Fennel

In a medium pot, heat the olive oil. Add the onion and sliced fennel and cook over moderate heat, stirring occasionally, until softened, about 5 minutes. Add the garlic and cook, stirring, until fragrant, about 3 minutes. Add the wine and cook over moderately high heat until almost evaporated, about 2 minutes. Add the escarole and water and bring to a boil. Cover and cook over low heat, stirring a few times, until the escarole is tender, about 10 minutes. Stir in the parsley, dill and lemon juice. Season with salt and pepper, garnish with the fennel fronds and serve.
