Eggplant Wheat Berry Casserole

Preheat grill for medium heat and lightly oil the grate.

Brush eggplant slices with about 1 tablespoon olive oil.

Grill eggplant on the preheated grill until tender and lightly browned, about 5 minutes per side.

Heat remaining 1 tablespoon olive oil in a pot over medium heat; cook and stir onion and garlic in the hot oil until onion is softened, 5 to 10 minutes.

Add chicken broth, wheat berries, barley, cinnamon, nutmeg, salt, pepper, and allspice to onion mixture; bring to a boil. Reduce heat, cover pot, and simmer until wheat berries are tender and some liquid is still remaining, about 40 minutes.

Preheat oven to 350 degrees F (175 degrees C).

Stir tomatoes and black beans into wheat berries mixture; remove pot from heat. Stir eggplant into wheat berries mixture; pour into a 9x9-inch casserole dish.

Sprinkle mozzarella cheese over mixture.

Bake in the preheated oven until cheese is melted, about 15 minutes.
