1. Prepare the Vegetables:

• Wash all vegetables thoroughly under cold water to remove any dirt or pesticides.
• Cut the zucchini into half-moons, bell pepper into 1-inch pieces, and red onion into wedges.
• Halve the cherry tomatoes and black olives.

2. Season the Vegetables:

• In a large mixing bowl, combine the cut vegetables.
• Drizzle with olive oil and sprinkle with dried oregano, salt, and black pepper.
• Toss everything together until the vegetables are evenly coated with oil and seasonings.
• If using, add balsamic vinegar for a tangy flavor.

3. Preheat the Air Fryer: Set your air fryer to 200°C (approximately 390°F). Let it heat for about 2-3 minutes.

4. Cook the Vegetables:

• Transfer the seasoned vegetables to the air fryer basket. Spread them out in an even layer to ensure they cook evenly.
• Cook for about 15-20 minutes. Shake the basket or use tongs to stir the vegetables halfway through the cooking time to ensure they roast evenly.

5. Final Touches:

• Once the vegetables are tender and slightly charred, remove them from the air fryer.
• Serve hot as a side dish. Optionally, sprinkle with feta cheese or pine nuts for extra flavor.
