Heat oven to 375°F Lightly spray cookie sheet with cooking spray. Mix cheeses and mayonnaise in small bowl until well blended and soft.
Separate dough into 2 long rectangles. Firmly press perforations to seal. Spread cheese mixture evenly over rectangles. Starting at short side, roll up each; pinch edges to seal. Cut each roll into 8 slices. Place cut side down on cookie sheet. Sprinkle with parsley.
Bake 12 to 15 minutes or until golden brown. Immediately remove from cookie sheet. Cool 3 minutes. Serve warm.
