Yes! You can make the salad dressing up to 7 days in advance. Store it in an airtight container in the refrigerator until ready to use. Homemade parmesan and croutons can be made up to 5 days in advance. These should be stored separately in airtight containers at room temperature. If you are looking for a lunch that will last you several days, make a big batch of the croutons and dressing. When it is time to make the salad, heat up the soy curls (if using), chop the lettuce, and toss everything together.
