In this quick grilled vegetable side dish recipe, tart sumac lends a slightly fruity but sour flavor. Paired with the garlicky mayo, it's delicious served alongside grilled fish. If you can't find sumac, try using cumin or paprika instead.
Preheat grill to medium-high.
Heat 1 tablespoon oil in a small skillet over medium heat. Add garlic and 1 teaspoon sumac; cook, stirring, until fragrant, about 1 minute. Transfer to a small bowl; whisk in mayonnaise.
Toss eggplant with the remaining 2 tablespoons oil in a large bowl. Season with salt and the remaining 1/2 teaspoon sumac. Grill the eggplant and lemon wedges, cut-side down, turning once, until tender, 5 to 6 minutes total.
Transfer the eggplant to a serving platter. Squeeze the grilled lemon over it. Sprinkle with cilantro. Serve with the sumac aioli.
Tips: The tart red berries of the Mediterranean sumac bush add fruity, sour flavor to many regional dishes. Find ground sumac in Middle Eastern markets, specialty-food shops and online.
