Cook the corn cobs in a large pan of boiling water for 5 mins. Remove the pan from the heat and leave the corn in the water until ready to grill.
Heat a grill using direct heat. Just before serving, remove the cobs from the water, pat dry and brush all over with mayonnaise and chilli flakes. Season to taste, then cook for 5 mins, turning regularly until grill marks appear. Sprinkle the cobs with KEFALOS Feta or Kefalotiri Cheese and coriander, then serve immediately with lime wedges to squeeze over when eating.
