Lightly grease the cooking plates of the cake pop maker.
In a large bowl, combine the chicken breast, pears, walnuts, cheese, dried cranberries and Italian seasoning.
Unroll the puff pastry sheet out and cut out circles (a bit bigger than the holes of your cake pop maker), You can use a small cup or cookie cutter. Alternatively, you can just cut them into about 24 equal squares with a pizza cutter.
Fill each circle with about one teaspoon of the filling and close it up. Shape them into balls with your hands.
Place them in the preheated cake pop maker and bake for 4 minutes. Flip them over and bake 1 to 2 more minutes, until golden brown all over. (Careful here as the cake pop maker does get hot - you can use heat gloves and a spatula.)
Let the chicken balls cool for a few minutes, as they will be hot in the center. Mix up the sauce ingredients and season, to taste.
Serve the puff pastry chicken balls with the sauce.
Notes
Store leftover chicken balls in an airtight container in the fridge for up to 4 days.
They can be reheated in the microwave or a low oven.
