How do Muslims begin a meal with prayer?

What is the procedure for beginning a meal with a prayer in a Muslim household? What are the words one would say (translated into English) as part of the traditional prayer?

Before a meal, we recite ‘Allahumma bariklana feema razaktana warzukhna khairan minhu. bismillahi wa’ala barakatillahi’
Meaning:
‘O Allah, bless it(the food) for us and feed us better than it.I begin in the Name of Allah with the Blessings of Allah’

I was taught this prayer by our mentor when I was 4 years old. ymoham3 and Moez are right too.

‘Bismillah ir-Rahman ir-Rahim’ which means "In the name of God, most Gracious, most Compassionate"
Muslims often utter this phrase before they set out to do anything.

After a meal:
‘Alhamdulillahi Rahman nir Rahim.’
Meaning:
‘ All praise to God, the most merciful and compassionate.’
