It's hard not to think of lettuce but as a backdrop for salad, a prop for "the goodies" such as tomatoes, cucumbers, radishes, etc. And the lettuce that is picked elsewhere and shipped to where we are shouldn't be expected to be much more than that; the most you can ask of it is to be crisp and bright.
The part I remembered most was that the lettuce tasted so ALIVE, that it didn't need a splash of balsamic vinegar to perk it up. The advantage to not using vinegar to dress the salad was that the acid in the vinegar would not ruin the tongue for the light wines we had with lunch. (That is also the reason that many French people serve the salad after the main course, to more fully enjoy the wine with the meal.)
So while the weather is reasonably cool, I grow lettuce in my flower boxes (the photo was taken this morning) where the bunnies can't get to it. I've been just clipping the leaf lettuces as needed for salads, and tearing off a few leafs of romaine for sandwiches and tacos. I'll harvest all of it before I take off for California over Memorial Day, and then plant again the week before Labor Day for the fall crop.
