Wash the eggplant and roast it over charcoal, a gas burner, or under the broiler until the skin is charred and the eggplant is soft. Cool.
Peel off as much skin as you can.
Cut the flesh into strips less than 1 inch (2.5 cm) wide, removing blackish seeds if there are many. Drain in a colander set over a deep dish for at least 30 minutes.
When liquid stops shedding, move eggplant to a bowl and toss with garlic, peppers, cucumber, parsley, olive oil, lemon juice, and black pepper. Add salt only when ready to serve.
