Salt the aubergine slices and leave in a colander to remove bitterness. Wash, drain and dry them well. Heat some olive oil in a wide, non-stick saucepan and sauté the vegetables in the following order: potatoes, courgettes, onions, peppers and finally the aubergines (whenever necessary, add oil to the saucepan). Remove vegetables with a slotted spoon.
In a bowl, mix tomatoes with parsley, garlic, salt, pepper, sugar and remaining oil. Place sautéed vegetables in a baking pan and pour tomato mixture on top.
Cover with aluminium foil and cook in a pre-heated oven at 200°C for 1 hour. Then remove the aluminium foil, stir the vegetables carefully and put back into the oven to brown.
Briam has become a must when we talk about "comfort food". As all vegetable dishes, briam can be eaten either warm or cold and it goes perfectly with a large piece of feta cheese.
