Roast the jalapeño, I do it directly over the stove flame, as we do in Mexico, but you can also put it in the air fryer for a couple of minutes. Remove the skin and the seeds
In the blender, place the mayonnaise, yogurt, and jalapeño, blend until smooth, and this will be our dressing.
Mix the tuna with the corn and add the dressing.
Finely chop the spring onions and add them to the salad, mix everything together, and serve.
