Pre-heat oven to 325°F.
Place one chicken breast into a medium-sized plastic baggie and gently pound until about 1/8 of an inch thick.
Remove from bag and lightly season with salt and pepper.
Repeat with each chicken breast.
Remove frozen herb butter roll from the plastic wrap and cut into 6 equal pieces.
Place one on each chicken breast and roll chicken breast up around it.
Secure it with a toothpick.
Prepare 3 shallow bowls, one with flour, one with eggs and one with breadcrumbs.
Roll each chicken breast first in flour, then dip generously into beaten eggs and finally roll in breadcrumbs, applying gentle pressure to ensure good coverage.
Over medium heat, panfry chicken in vegetable oil and additional butter until golden brown.
Bake for about 40 minutes; temperature inside chicken should reach 180°F.
Remove toothpicks and serve immediately.
