Build a medium direct fire. Spread an even layer of unlit charcoal in the bottom of the grill. Fill a chimney halfway with charcoal. Stuff two sheets of newspaper in the bottom of the chimney and light it. When the coals are fully engaged-you should see flames peeking over the top-pour them over the unlit charcoal. If using a gas grill, light the gas and adjust the temperature on both sides to medium.

Lightly oil the zucchini and season with salt and pepper.

When you can hold your hands over the fire for no more than 5 to 8 seconds, clean the grill grate. Place the zucchini on the grill and cook for 30 seconds (2 minutes if doing 1/2" slices), flip and cook for an additional 30 seconds, until golden brown. Remove from heat and place in a bowl.

Add the remaining ingredients to the zucchini and toss very gently to combine. Sprinkle sea salt over the salad and serve immediately or set aside at room temperature until serving time.
