Chop courgette into rings.
Make a marinade of olive oil, garlic, some chilli and basil or thyme, whatever you feel like. Drown the courgette circles in the marinade, making sure, all pieces get covered well. Leave for a couple of hours.
Lay the circles on an oven pan and cook in a preheated oven at 200*C for 10-15 minutes. If you sprinkle some grated cheese on top, the cheese will tell you when it's time to get the courgettes out by melting.
Nice with some grilled meat!
