Spinach Hand Pies

Place the washed and dried spinach leaves into a blender, then add the melted butter, milk, vegetable oil, and egg.

Blend everything until completely smooth.

Pour the mixture into a mixing bowl, and stir in the sugar, salt, and baking powder.

Gradually incorporate the flour and knead until a smooth dough forms.

Divide the dough into portions, and roll them out using a rolling pin or your hands.

Place the cheese in the center and tightly seal the edges.

Arrange the pies on a baking sheet lined with parchment paper, and brush with egg yolk.
