Mix together the cream cheese and buffalo sauce, and divide the mixture between the tortillas, then spread to the edges.

Top with chicken, then cheese.

Sprinkle green onions around.

Start from one end, and tightly roll the tortilla into itself. 

Wrap in saran wrap and refrigerate for 1 hour, or until ready to serve.

Once ready to serve, use a serrated bread knife to cut into 6 one inch pieces, discarding (or snacking on) the ends. Arrange on a platter to serve.
