How to Make It
Heat a grill pan. In a medium bowl, toss the zucchini with 2 teaspoons of the olive oil and season with salt and pepper. Grill the zucchini over moderately high heat until grill marks form, about 2 minutes. Turn the zucchini and grill until tender, about 2 minutes. Transfer the zucchini to a plate.
In a small bowl, mix the remaining 1 tablespoon of olive oil with the lemon juice and season with salt and pepper. Spoon the dressing over the zucchini, sprinkle with the chives and thyme and serve.
