Swiss Chard Slab Pie
This crowd-pleasing recipe by Justin Chapple comes from Kristin Donnelly's book "Modern Potluck" and makes the most of Swiss chard, using both leaves and stems to fill a vegetarian slab pie with a buttery, peppery crust. That filling, tangy with reduced white wine and bound with sour cream, tastes just as good warm as it does cold, and can feed a crowd any time of day. Note: Wash leaves and stems thoroughly to avoid any traces of grit in the finished pie.

Instructions
Step 1
Make the dough: In a food processor, pulse flour with salt and pepper. Add butter and pulse until mixture resembles a coarse meal, with some large pieces of butter remaining. Sprinkle ice water on top and pulse just until dough comes together. Scrape onto a work surface, divide in half, and pat each half into a 6-inch square. Wrap in plastic wrap and chill for about an hour.Step 2
Make the filling: In a pot, heat olive oil over medium-high heat. Add onion, garlic and a generous pinch of salt, and cook, stirring occasionally, until just softened, about 5 minutes. Add coriander, ginger and red pepper flakes. Add chard stems and cook until just softened, about 6 minutes. Stir in chard leaves in large handfuls, letting them wilt before adding more. Add wine, reduce heat to medium, and cook until leaves are tender and liquid has evaporated, about 15 minutes. Transfer to a colander to cool completely and drain. When cool, mix chard with sour cream and season with salt and pepper.Step 3
Heat oven to 400 degrees. Line a large rimmed baking sheet with parchment paper. On a lightly floured work surface, roll out one piece of dough to a 12-by-16-inch rectangle. Slide dough onto parchment-lined baking sheet. Spread filling evenly, leaving a 1-inch border. Roll out remaining dough and ease it over the filling. Fold the rim over itself and pinch edges to seal. Cut a few slits in the top of the pie and brush with egg wash.Step 4
Bake for 50 to 55 minutes, until crust is golden and cooked through. Let cool for at least 15 minutes before cutting. Serve warm or at room temperature.
