The new menu, called Freshside Grille, is lower in fat and calories than the quick-serve seafood chain's standard fare. Entrees and side dishes will include grilled Pacific salmon, shrimp scampi, mixed vegetables and seasoned rice.

Louisville, Kentucky-based Long John Silver's will begin introducing the new menu in late October at its U.S. restaurants.
