Preheat a grill or grill pan to medium.

Place the zucchini on a large plate or tray, drizzle with olive oil, and sprinkle with the garlic powder and pinches of salt and pepper. Toss to coat.

Grill for 1 to 3 minutes per side, or until char marks form and the zucchini is tender but still has some bite.

Remove from the grill and squeeze with lemon juice. Garnish with fresh herbs, season to taste, and serve.
