Pour ⅓ of the tomato sauce in a 9"x13" baking pan or into individual baking dishes and spread it across the bottom.
Arrange half the eggplant slices on top of the sauce. Sprinkle half of the cilantro over the eggplants and then layer half of the tomato slices evenly over the eggplant.
Pour on the other ⅓ of the sauce. Repeat with the remaining eggplant, cilantro and tomato slices. Finish the dish by drizzling the last ⅓ of the sauce making sure to cover all the veggies.
Cover the dish tightly with aluminum foil and bake for about 20~30 minutes or until the mixture is bubbly; then remove the foil and bake for another 5 minutes. Remove from the oven and cool slightly before serving. Top with garlic yogurt just before serving.
