Before eating a meal, say:
Christ, Bread of Life,
Come and bless this food. Amen
Or
Bless us, O Lord, and these your gifts, which we are about to receive from your bounty;
through Christ our Lord. Amen
After a meal, say, as you make the Sign of the Cross:
+ May the Lord, who has fed us on earth,
bring us to share His banquet in heaven. Amen
