This is a classic French sandwich. It's saucisson sec (dry salami) on a piece of baguette (French bread) that has been spread — lightly, of course — with butter. When I lived in Paris years ago, it was called un sec beurre. It's what I made to take with me as my lunch when I rode the train to Paris at noon on Sunday.
I'm writing this from North Carolina. I went to Paris on Sunday to spend the night there before catching my flight to the U.S. on Monday. So here I am in America. In Paris, I stayed in a hotel near the Sorbonne Sunday night. They put me in a room on the 7th floor. With no elevator. I had to lug my heavy suitcase all the way up there. And back down. At my age, that was a challenge.
Sunday afternoon I went to the theater in Paris. I had decided to buy a ticket to a play in case it was rainy and cold outside that day — November 1, after all — making it not pleasant just to go for a walk around the city. I didn't want to be bored. Sunday afternoon turned out to be fantastically sunny and warm in Paris, but I'm glad all the same that I went to see the play. It was a lot of fun, and something I've done just a few times in my life. More about all that over the next few days and weeks.
