I'm going to move on to idioms about the weather, geography, and in general, the environment. Food idioms, both those used on this blog and many that have not, will be gathered in an upcoming eBook that I will call Food for Thought - Expressing Ourselves Through Food . Most of the preparation work is complete. It is not fully ready yet, and I have not decided on a price, but it will not be a free eBook - I will be selling it for a small, fair price. I have to put food on the table, too :) - Jeremiah Bourque
And yes, putting food on the table is itself an expression. It means earning enough money to fulfill normal, everyday life needs.
