Gather a large mixing bowl and add flaked imitation crab, julienned carrots, shredded cabbage, drained canned corn, and finely chopped fresh parsley. Combine to create a colorful medley.

In a small bowl, whisk together mayonnaise, freshly squeezed lemon juice, garlic powder, onion powder, ground black pepper, and a pinch of salt until smooth and creamy.

Pour the dressing over the mixed salad ingredients and gently toss everything together using tongs until coated.

Cover the bowl tightly with plastic wrap and refrigerate for at least two hours to allow flavors to meld.

Before serving, give the salad a gentle toss, transfer to a serving bowl, and sprinkle with additional toasted sesame seeds.
