The shorter form of the Dominican Grace Before Meals most commonly prayed is "May the Giver of all good things bless the food and drink of His servants. Amen." The Latin version of this shorter form is: "Largitor omnium bonorum benedicat cibum et potum servorum suorum. Amen." It is noteworthy, however, that the more distinctly Dominican form of this prayer was traditionally said when blessing diluted wine to be used for the evening meal during periods of fasting, and does not include cibum, food, but just potum, drink - as follows: "Largitor omnium bonorum benedicat potum servorum suorum. Amen."
In case you are looking for a Latin version of the grace before meals prayer of "Bless us, O Lord, and these thy gifts", etc., that can be found here.
I had difficulty finding the Dominican Grace Before Meals in Latin online previously, so when I found a placard with a traditional series of such prayers, I thought I might post them. The placard is kept in the refectory at St. Albert's Priory, the Dominican House of Study in Oakland, California.
The prayers from the placard are as follows:
