Preheat the oven to 400 °F. Cover the baking tray with baking paper. Using the bamix®, mix the chicken, cream cheese, grated cheese, chili peppers, onion and seasonings in the SliceSy®.
Roll out the dough 3–4 mm thin on a floured worktop. Cut out circles of about 4 inches each in diameter. Place one teaspoon of the filling in the center. Using the bamix® with the whisk attachment, beat the egg and brush it onto the edges of the dough. Fold the dough over the filling to form a semicircle.
Firmly press down the edges with a fork. Place the empanadas on the baking tray and brush on the rest of the egg. Cut a small, ½ inch slit on the top of the dough. Bake the dough buns for 12–15 minutes until golden brown. Serve with your favorite condiments like salsa or sour cream.
