To a salad spinner or large container, add 5 cups greens of choice, sliced cucumber, 1 cup celery, 1/2 cup carrots and 1 1/2 cup tomatoes. Toss everything to combine and mix well.
Toss with dressing and garnish with croutons, nuts or seeds, and olives, if using.
If eating salad as leftovers, wait to toss with dressing and any optional garnish (croutons, olives, etc) until ready to eat.
