Cut the zucchini into 3mm thick slices. Layer in a fan shape on a baking sheet lined with baking paper. Salt and pepper, sprinkle with chopped garlic and drizzle generously with olive oil.
Grill under the grill for about 10 minutes. Tastes great with pan-fried meat that has been drizzled with balsamic reduction. In addition, e.g. baked potatoes with herb quark.
