Poach Chicken. Place chicken in in a pan just large enough for chicken to fit in single layer. Cover with water and season with salt and pepper. Bring to boil then reduce heat so water barley bubbles. Cook for 10 minutes. Remove from heat and cover for another 10 - 15 minutes.

In a medium saucepan, melt 1/2 of the butter over medium heat. Add flour and cook, stirring, for 1 to 2 minutes without browning. Gradually whisk in milk and broth; cook, stirring constantly, until smooth and thickened. Remove from heat; let cool 5 to 10 minutes.

In large bowl, combine chicken, 1 cup bread crumbs, parsley, salt and eggs. Mix well. Pour in sauce, blend well. Cover and chill for about 2 hours.

Preheat oven to 350°. Combine Mozzarella cheese and remaining 1/4 cup bread crumbs in a shallow dish.

Shape chicken croquettes mixture into 2 1/2-inch balls, then roll to form oval shapes; makes about 8. Roll shaped croquettes in bread crumb mixture. Arrange in a greased 13 x 9 x 2-inch baking dish. Melt remaining butter and drizzle over chicken croquettes. Bake chicken croquettes 30 minutes until golden brown.

For gravy I just used McCormik's Chicken gravy packets which we really like and is easy to make.
