Preheat the oven to 350°F (175°C) and line a baking sheet with aluminum foil, spraying it with non-stick spray.

Gently pound chicken breasts to an even thickness of about half an inch.

In a mixing bowl, combine softened goat cheese, mayonnaise, chopped sun-dried tomatoes, minced garlic, dried basil, kosher salt, and black pepper until smooth.

Stuff each chicken breast with approximately two tablespoons of the filling, securing edges if needed.

In another bowl, mix panko breadcrumbs with mayonnaise and dried basil; coat each stuffed breast thoroughly.

Place the coated chicken on the prepared baking sheet and bake for 25 minutes or until golden brown and cooked through (165°F internal temperature).

Let rest for 5 minutes before slicing and serving.
