Lettuce and sorrel to wash, dry with paper towel, to break hands into small pieces.

Apple wash, remove core, cut into strips, drizzle with 1 tbsp of lemon juice.

Mix the lettuce, watercress and Apple, mix gently. For dressing mix 1 tbsp lemon juice and sugar. If you want to keep the acidity, the sugar is added. For example, I liked the sweet and sour taste.
