Place the ears of corn on the hot grill pan and grill them for 8-10 minutes, turning each over every couple minutes so they are a little browned (see photo below).
Drizzle with 2 tsp olive oil and continue to cook until tender.
Let cool.
When the corn is cool, using a sharp knife, cut the kernels (see photo below) right onto a plate.
Transfer the corn kernels to a bowl and set aside.
Place all the dressing ingredients into a little bowl and stir well.
Pour the dressing over the corn kernels and toss gently to combine.
Place in individual little bowls and top with a slice of lemon and a fresh sprig of mint.
