This is one of the simplest (maybe THE simplest) salad imaginable. It only has three ingredients! When I was a kid, we often had this salad as a side during the summer. My mother would usually use Boston lettuce, but any lettuce works fine.
1 large Romaine lettuce (or Boston lettuce, Romaine hearts, iceberg lettuce,...)
3-4 tbsp lemon juice
2-3 tbsp sugar
Dissolve the sugar in the lemon juice. Tear or cut the lettuce in pieces. Toss lettuce and dressing and serve.
