The secret to perfectly tender eggplant is salting before you cook. Here, flame-kissed slices are topped with a simple tomato salad for a satisfying vegetarian main course.
Generously season eggplant slices with salt. Place vertically in a colander, overlapping them. Let stand 30 minutes; rinse and pat dry.
Preheat grill to medium-high. Liberally brush cut sides of eggplant with oil. Grill, turning once, until tender, about 4 minutes a side. Mix tomatoes, pine nuts, feta, red-pepper flakes, and oil; season with salt. Spoon over eggplant; top with basil.
