INGREDIENTS2 tablespoons olive oil, plus more for drizzling
1 medium yellow onion, diced
1 medium bulb fennel, quartered, cored, and thinly sliced
2-3 cloves garlic, finely chopped
1 medium bunch Lacinato kale, stems removed, chopped into bite-sized pieces
1/3 cup crumbled feta cheese, plus more for topping
1/4 cup kalamata olives, pitted and finely chopped
2 tablespoons chopped fresh parsley
Fresh ground black pepper
1 17-oz. package (2 sheets) puff pastry, thawed
3 tablespoons unsalted butter, melted
INSTRUCTIONS1. Heat oil is a large pan over medium heat. Add onion and cook, stirring occasionally, until softened and lightly browned, 5-7 minutes. Add fennel and garlic and cook, stirring occasionally, until softened, 5 minutes. Lower heat; add kale, cover pan and cook until kale is soft and wilted, adding a teaspoon of water if necessary, about 5 minutes. Remove pan from heat and fold in feta, olives and parsley. Season with pepper to taste.
2. Preheat oven to 375° and line two baking sheets with parchment paper. Unroll both puff pastry sheets onto a floured work surface. Cut each sheet into 9 squares. Cut L-shaped slits on opposite corners of each square (creating a frame-like shape). Take hold of both corners and fold them toward the opposite side, passing one corner under the other and pressing them in place, to create a diamond-shaped pocket to hold the filling.
3. Mound 1-2 tablespoons of filling into each pocket; top with a little more feta and a drizzle of olive oil. Place pockets on the prepared baking sheets and brush the outer edges with melted butter. Bake until golden brown and puffed, 30-35 minutes. Serve warm, topped with more feta if you like.
