Preheat a grill or grill pan over high heat.

Step 2

Season the eggplant with salt on both sides and let sit for 5 to 10 minutes while you prepare the other ingredients.

Step 3

Place the ciabatta on a rimmed baking sheet and brush the split sides with some of the olive oil and season with salt. Add the scallions and coat with some of the olive oil and season with salt.

Step 4

Pat the eggplant dry and drizzle both sides with some of the olive oil. Grill the eggplant until softened and charred, 5 to 6 minutes per side.

Step 5

Grill the scallions until softened and charred, 2 to 3 minutes per side. Cut the charred scallions into 1/4 inch pieces.

To build the sandwich, rub the garlic on the split sides of the toasted ciabatta. Spread the hummus on the split sides. Add the eggplant and scallions to the bottom half of the ciabatta. Top with the feta, arugula, basil, and dill. Squeeze lemon over the arugula and herbs, then sprinkle with black pepper. Close the sandwich, slice, and enjoy!
