Instructions

1. Heat olive oil in a large skillet over medium heat. Add shallot and cook until softened, 3–4 minutes. Add garlic and cook 1 minute.
2. Add chopped mushrooms and cook until moisture evaporates and mushrooms brown, 8–10 minutes. Stir in cooked lentils, walnuts, spinach, soy sauce, balsamic vinegar, thyme, salt, and pepper; cook until spinach wilts and mixture is cohesive, about 3 minutes.
3. Remove from heat and stir in breadcrumbs. Cool mixture to room temperature (about 15 minutes).
4. Preheat oven to 400°F (200°C). On a lightly floured surface, roll puff pastry into a rectangle large enough to enclose the filling. Place cooled filling lengthwise in center of pastry and fold edges over to seal, trimming excess. Place seam-side down on a baking sheet.
5. Brush pastry with almond milk and cut a few small vents on top. Bake until pastry is golden and crisp, 30–35 minutes. Let rest 10 minutes before slicing and serving.
