In a spacious bowl, combine the drained sweetcorn, finely chopped red onion, diced red bell pepper, diced cucumber, and chopped cilantro.
Whisk together the lime juice, olive oil, salt, and pepper in a smaller bowl. Adjust the seasoning according to your taste.
Drizzle the dressing over the vegetables in the larger bowl. Gently toss everything together to ensure even coverage.
Allow the sweetcorn salad to rest for approximately 10 minutes before serving, enabling the flavours to meld.
Just before serving, give the salad a final toss and adjust the seasoning if required.
Present the sweetcorn salad as a revitalizing side dish or a light snack.
