01 - Preheat a grill or grill pan to medium-high heat.
02 - In a small bowl, combine the olive oil, minced garlic, dried oregano, sea salt, and freshly ground black pepper. Mix well until evenly blended.
03 - Using a basting brush, generously brush both sides of each eggplant and tomato slice with the marinade mixture, ensuring even coverage.
04 - Place the eggplant slices on the preheated grill. Cook for 4–5 minutes per side until tender and deep grill marks appear.
05 - Grill the tomato slices for about 2 minutes per side until just softened but still holding their shape.
06 - Arrange the grilled eggplant and tomato slices on a serving platter, alternating layers. Drizzle with balsamic glaze and sprinkle with fresh basil chiffonade before serving.
