Preheat the oven to 350°F (175°C).

In a bowl, combine the diced chicken, crumbled bacon, chopped mushrooms, chopped pecans, diced apple, mayonnaise, salt, and pepper.

Cut the bread into rounds and press them into muffin tins to form baskets.

Brush the bread baskets with melted butter.

Bake the bread baskets in the oven for 15 minutes, or until golden brown.

Remove the baskets from the oven and let them cool.

Fill each bread basket with the chicken salad mixture.

Garnish with minced parsley before serving.
