Notes
Seasonings, especially salt, are guidelines. Adjust to taste.
You can add protein, such as chicken or shrimp, to turn this salad into a main-dish salad.
Cherry tomatoes are an optional ingredient. I don't always use them, but when I have them on hand, they do add a pretty splash of color to the salad.
You can assemble the salad a few hours in advance, loosely cover it with paper towels, and refrigerate it. Don't add the dressing until the last minute, or the greens will become soggy.
As with all salad greens, once the salad is ready and you've added the dressing, I don't recommend keeping its leftovers, as the leaves will wilt.
