Prepare the filling by heating olive oil in a skillet over medium heat. Add onion and bell pepper; sauté until softened. Add garlic, cumin, and paprika; cook until fragrant.
Stir in black beans, tomato paste, and water. Simmer until liquid evaporates. Mix in corn, scallions, and cilantro. Season with salt, pepper, and hot sauce.
Preheat oven to 400°F (200°C). Roll out puff pastry and cut into 4 ½-inch circles.
Place filling in the center of each circle, fold over, and crimp edges with a fork. Brush with almond milk.
Bake for 20-25 minutes, brushing with olive oil or vegan butter 5 minutes before done.
