In a large mixing bowl, mix the cream cheese, mayo, Dijon, garlic powder, salt, and pepper together until smooth.
Add the chicken, dried cranberries, pecans, celery, and chive to the bowl. Stir until evenly combined. Check the seasoning and add salt and pepper to taste.
Lay out a tortilla and add 1/4 of the chicken salad to the center. Spread the chicken salad evenly over the tortilla, leaving a 1/2-inch border around the edge. Repeat with the remaining tortillas and salad.
Tightly roll each tortilla into a log. Wrap with plastic wrap and place in the fridge to chill for at least 1 hour.
Unwrap the tortillas. Slice off the end and then cut each log into 6 pinwheels. Arrange on a serving plate and garnish with more chives, if desired.
