Saying Grace before meals

When I was in rehab (15 years ago) I was at a Camp Hill community. It wasn't really that helpful for my drug problem. Maybe I wasn't ready at the time and because I don't believe in God, I had a lot of resistance to the antroposofic cosmology . Also, Camp Hill is very hierarchic and not really a drug treatment program; it's for mentally disabled people. I find Buddhist meditation practices on non-self, suffering and impermanence much more helpful. What I did like about Camp Hill was that we always had a little prayer before meals. When I am about to eat, I very often wish I could have some kind of Saying Grace that could express gratitude (I don't know if 'Saying Grace' is the right term, in Norwegian it's called "table prayer"). Does anybody know any Buddhist prayers like that? It's not so important what tradition it comes from.
