As long as you don’t apply the salad dressing, salads can be made ahead and saved for later.
Simply assemble the salad minus the dressing, wrap with plastic wrap and refrigerate till ready to dress and eat.
We often do this. Sometimes we don’t want a salad now, but know we’ll want one later, while also knowing that later we won’t feel like making the salad.
These later salads solve the dilemma.
And yes, they stay fresh as long as you start with fresh, crisp ingredients.
