2 tablespoons olive oil 1 bunch swiss chard, trimmed and stems removed and cut, leaves cut into 2-inch ribbons 1 large large shallot, thinly sliced (about 3/4 cup) Kosher salt and freshly ground black pepper Pinch of dried red chile flakes 4 1/2 cups homemade vegetable stock or store-bought low-sodium vegetable broth 1 pound whole wheat fusilli pasta 2 tablespoons fresh juice and 1 tablespoon zest from 1 lemon Parmigiano-Reggiano, for grating
Preparation:
Heat the oil in a 12-inch skillet over medium-high heat until shimmering. Add the chard stems and season with salt and cook until they begin to soften, about 3 minutes. Add the shallots and cook until they have softened, adding another pinch of salt and the red chile flakes, about 2 minutes.
Add the stock to the pan with the fusilli and adjust the heat to maintain a vigorous boil and cook according to the package directions until the pasta has about 4 minutes left in the cooking process. Then, stir in the chard leaves and cook until the pasta and chard are done. Stir in the lemon juice and zest and adjust the seasoning as needed.
