Begin by shredding the green cabbage thinly to ensure each bite is crisp and tender. Next, chop the cucumber and celery into small, bite-sized pieces. Finely chop your choice of fresh herbs, like cilantro or parsley, for an added touch of flavor.

In a medium bowl, whisk together the mayonnaise and vinegar until smooth and creamy. Add salt, black pepper, and onion powder, mixing to ensure the spices blend evenly into the dressing.

Once your vegetables and dressing are ready, toss the chopped cabbage, cucumber, celery, and herbs together in a large bowl. Pour the dressing over the mixture and gently fold everything until the vegetables are well coated.

Cover the bowl with plastic wrap and refrigerate the coleslaw for at least 1 hour to allow the flavors to meld.
