01 - Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper to prevent sticking.
02 - Toss the diced zucchini, bell peppers, red onion, and eggplant with olive oil, salt, and black pepper in a large bowl.
03 - Spread the seasoned vegetables evenly on the lined baking sheet. Roast for 20–25 minutes, stirring halfway through, until tender and slightly caramelized. Allow to cool slightly.
04 - Place couscous in a heatproof bowl. Add 1 cup of boiling water, salt, and olive oil. Cover tightly and let sit for 5 minutes. Fluff gently with a fork.
05 - In a small bowl, whisk together the extra virgin olive oil, lemon juice, minced garlic, dried oregano, salt, and pepper until fully emulsified.
06 - In a large serving bowl, combine the fluffed couscous, roasted vegetables, cherry tomatoes, Kalamata olives, crumbled feta, parsley, and mint.
07 - Pour the lemon-herb dressing over the salad. Toss gently to coat all ingredients without crushing the vegetables. Serve warm, at room temperature, or chilled.
