Cut the bell pepper into large cubes (may be 3 by 3 cm) or rings (max 1 cm thick) – whichever you prefer.
Cut the eggplant and tomatoes into slices of maximum 1 centimeter
Do you like grilled eggplants? Drizzle the slices of aubergines with olive oil and grill briefly on the bbq (high heat). Ideally, you'll see a nice grill on the slices. Don't let them cook because they still have to be put in the oven! Put them aside for a while
Fry the onion and garlic briefly in olive oil
Add the bell pepper fairly quickly
Let it simmer for a few minutes
Take a casserole dish and colander the garlic/onion/bell pepper in the casserole.
Pour the spices over the dish
Place the aubergines and tomatoes on top. You can choose either a layer of eggplants and on top of that the tomatoes or you can take turns putting them on top.
You can sprinkle some herbs on top.
Place in the oven for 45 minutes. Add the grated cheese for the last 5 minutes.
