I've shared this on Tumblr and a number of people liked it. I've even used it with my Catholic convert mom to much approval! Feel free to use it, and if you want to add on to it to invoke the name of your deity/ies when you pray it, feel free to.

May the bounty we have in front of us and the deep gratitude we feel about it inspire us to work for justice so that all may have food on their tables, tables under their roofs, and roofs over their heads every night.
