1. Place the Oreo cookies in a food processor and pulse until fine crumbs form. Alternatively, crush them in a ziplock bag using a rolling pin.

2. In a bowl, combine the crushed Oreos with softened cream cheese and vanilla extract. Mix until a dough forms.

3. Roll the dough between two parchment sheets into a thin rectangle about 1/4 inch thick.

4. Transfer to the refrigerator and chill for 20 minutes. Then trim edges and slice into long strips.

5. Roll each strip into a spiral to create the sushi effect.

6. Drizzle with melted chocolate if desired. Chill for another 10 minutes before serving.
