How to Make It
Preheat broiler with an oven rack 6 inches from heat.
Heat a large cast-iron skillet over medium-high. Add 2 tablespoons oil; swirl to coat. Add tofu; cook until browned, about 5 minutes. Remove tofu from skillet. Add 1/4 cup oil and eggplant slices in a single layer; cook, without stirring, until browned, about 4 minutes. Flip eggplant slices; cook until tender, about 4 minutes. Remove skillet from heat.
Combine tomatoes, garlic, oregano, cinnamon, cumin, salt, and crushed red pepper in a medium bowl.
Top eggplant evenly with tofu. Spoon tomato mixture over eggplant and tofu. Drizzle with remaining 1 tablespoon oil; sprinkle with feta. Broil until cheese begins to brown, about 4 minutes. Garnish with chopped mint and oregano.
