Preheat oven to 200˚C / 400˚F.
In a large bowl, add the corn, mayonnaise, half of the scallions, gochugaru or chili/pepper flakes, sea salt and a big pinch of black pepper. Stir until well combined.
On a sheet pan (baking sheet), add the corn chips, spreading them out into an even layer. Dollop the corn mixture evenly across the corn chips. Place into the oven and bake until the cheese is melted and turning golden, about 10-12 minutes.
Remove from the oven and top with remaining scallions. Serve immediately.
