These were on a silverware envelope at a Mexican food restaurant in San Antonio. I found them interesting.

Protestant
Bless, O Lord, this food to our use, and us to thy service, and make us ever mindful of the needs of others, in Jesus Name, Amen.

Catholic
Bless us, O Lord, and these Thy gifts, which we are about to receive from Thy Bounty, through Christ our Lord, Amen.

Jewish
Lift up your hand toward the sanctuary and bless the Lord. Blessed art Thou, O Lord our God, King of the universe, who bringest forth bread from the earth, Amen.
