2. Wash the tomatoes and cut them into cubes. Wash the lettuce and separate the leaves.
3. Arrange the lettuce leaves on the plates, add the grilled eggplant slices, tomatoes, and feta cubes. Optionally, drizzle with olive oil and lemon juice. Enjoy this original recipe for a light lunch or dinner.
