This is the one that we have in our Kitchen, i'm not sure if your Christian, but if you are, this one is ideal:
(My Kitchen Prayer
Bless my little kitchen lord.
I love it's every nook.
And bless me as I do my work,
Wash pots and pans and cook.
May the meals that I prepare,
Be seasoned from above.
With thy blessing and thy grace,
But most of all they love.
As we partake of earthly food,
The table thou hast spread.
We'll not forget to thank thee lord,
For all our daily bread.
So bless my little kitchen lord,
And those who enter in.
May they find naught but joy and peace,
And happiness therein.
A quotation that I would put in my kitchen, although it is not related to food or cooking, is this:
May the road rise up to meet you.
May the wind be always at your back,
May the sun shine warm upon your face,
The rain fall soft upon your fields,
And until we meet again,
May God hold you in the palm of His hand.
- Irish Blessing
