Thaw dough and roll it gently. Cut into squares. Banana cut into slices and chocolate is broken. In each square put a piece of banana and 1-2 pieces of chocolate. The edges are coated with water, stooped and pressed well. Fry in oil until more readily, which is then removed on kitchen paper. Sprinkle powdered sugar and serve. In powdered sugar can be added and vanilla, and can be put and chocolate brown. In fact there are many options, but this is the original recipe.
