Core and chop the iceberg lettuce into bite-sized pieces and place in a large bowl.
Dice the cucumber, halve the tomatoes, slice the red onion, and chop the cilantro.
Add the prepared vegetables and cilantro to the lettuce and toss gently.
Whisk mayonnaise, olive oil, lemon juice, and parmesan in a small bowl until smooth.
Season corn kernels with paprika, salt, and extra parmesan in the air-fryer basket.
Air-fry at 400°F for 8–10 minutes, shaking halfway, until golden and crisp.
Pour dressing over the salad and toss to coat evenly.
Top with the hot air-fried corn, give a final toss, and serve immediately.
Tip: Dry the lettuce well so the dressing clings instead of thinning out.
Tip: Serve right away for maximum corn crunch.
