Fast food chains serve up fish specials for Lent

Some fast food chains are serving up fish specials for Lent.
Wendy's, Chick-fil-A and Arby's are among the companies introducing or re-introducing fish sandwiches for a limited time.
Lent is a six-week period of self-sacrifice and prayer observed by Christians.
Typically, individuals refrain from eating meat on Fridays through Easter.
