Well it was a frosty morning, gray and I was prepared to hunker down and stay inside all day. But a visit to the kitchen indicated that I was very likely going to starve by dinner time.
I'm usually very good at putting something together out of whatever's on the shelf but I came up with nothing. So got out of my comfies and drove up to the store.
Came back with a double arm load, which I weighed, because the bathroom scale was right there. My food cost: $4 a pound on average.
