As well, this is timely...
Recently, I received a cookbook on Zen Temple food - (it could be described as vegan japanese, if you want to put it in a box - though none of us would do that
... the most important thing, though, is the philosophy, which in part, includes the 5 reflections, (which you can find in other parts of the world in the buddhist tradition as well, I believe)
(Paraphrased from memory; i was running over this in my head on the way to work today)
1. May I reflect on where this food came from, the hands it has passed through, and those that prepared it.
2. Let me reflect on my imperfections, and whether I am worthy of this food.
3. Let me put aside all preferences and greed, and
4. Consider this food to be an effective medicine, to maintain the health of
my body and spirit
5. That it may help me in my work towards enlightenment.
(or for the work that God has for me - if that's more comfortable for you)
I want to practice this for a month (at least

) - I have found that this is more effective in my feeling thankful for my food, as well as my attitude towards what I choose to eat, than just a "standard" prayer which has been my practice for most of my life up until now.
Blessings!
