To one edge of the flattened chicken that is nearest to you add the chopped parsley, and the roasted red peppers, onions and spinach. Add to that spot only and not all over the chicken.
Using the wax paper, slowly roll the chicken into a log carefully tucking the ingredients in as you roll.

Drizzle the white sauce all over the log and then onto each slice served.
