Heat oil in a deep fryer to 350 degrees F (175 degrees C).

Place filets on a solid, level surface and pound with the smooth side of a meat mallet until 1/8- to 1/4-inch thick.

Place bread crumbs and flour in two separate shallow dishes, such as soup plates. Lightly beat eggs in a third shallow dish; add milk and lightly season with salt and black pepper.

Dredge filets in flour, patting lightly by hand. Dip into egg mixture, using a fork to hold filets; let excess drip off. Press into bread crumbs to coat both sides filets. Place breaded filets, unstacked, onto a plate.

Deep fry filets until golden brown.
