Wash the courgettes, grate them dry and cut them lengthwise into thin slices with a peeler. Let the zucchini slices simmer in boiling salted water for about 1-2 minutes, rinse in cold water. Drain and spread out on a clean tea towel to dry. Wash the thyme, shake dry. Cut cheese blocks in half, wrap them with zucchini strips and place 10 thyme stalks in between.
Brush aluminium foil well with oil, place on the grill and place wrapped cheese on top. Grill the cheese for about 15 minutes while turning it over until the zucchini takes on colour and the cheese is soft
Arrange cheese on plates with mango chutney and sprinkle with remaining thyme
