In a bowl, mix together cream cheese and softened butter until smooth. Mix in chicken, salt, pepper, milk, chives, onion and pimentos. Separate crescent rolls into rectangles.
Spoon chicken mixture over each rectangle. Fold dough over and press together to seal edges. Brush with melted butter and sprinkle with croutons.
Arrange on ungreased baking sheets. Bake at 350 degrees for 20 to 25 minutes, until golden.
