Although eating meat on Fridays during Lent normally is prohibited, this does not apply on Fridays that are solemnities. The Code of Canon Law provides that:
Abstinence from meat, or from some other food as determined by the Episcopal Conference, is to be observed on all Fridays, unless a solemnity should fall on a Friday. Abstinence and fasting are to be observed on Ash Wednesday and Good Friday (Can. 1251).
Since today–Friday–is the solemnity of St. Joseph, the law of abstinence doesn’t apply.
