The lettuce has come to the end of its life. I've noticed some leaves that are looking a bit sunburt and they have a silvery shine to them. The lettuce is becoming more stalk than leaf and it's basically just keeled over and died. Oh well, it was a short but very productive life!
Nevertheless, there were still a few good leaves left to go onto a sandwich for lunch. I hardly ever have sandwiches for lunch at home, but the combination of fresh bread and crisp, freshly picked lettuce is a hard match to beat.
