Ingredients

• 1 medium, sliced 1/2-inch thick Zucchini
• 1, sliced 1/2-inch thick Red bell pepper
• 1/2 medium, cut into wedges Red onion
• 1 cup Cherry tomatoes
• 2 tbsp Olive oil
• 3 tbsp Balsamic vinegar
• 1 tsp Dried oregano
• 1/2 tsp Salt
• 1/4 tsp Black pepper

Instructions

1. Step 1: Preheat oven to 425°F. Toss 1 medium sliced zucchini, 1 sliced red bell pepper, 1/2 medium red onion wedges, and 1 cup cherry tomatoes with 2 tbsp olive oil, 1/2 tsp salt, 1/4 tsp black pepper, and 1 tsp dried oregano in a large bowl.
2. Step 2: Spread vegetables evenly on a parchment-lined baking sheet, ensuring they're in a single layer without crowding.
3. Step 3: Roast for 25-30 minutes, stirring once halfway through, until edges are caramelized and vegetables are tender when pierced with a fork.
4. Step 4: Transfer roasted vegetables to a serving dish, then simmer 3 tbsp balsamic vinegar in a small saucepan over medium heat for 5-7 minutes until reduced by half and syrupy.
5. Step 5: Drizzle reduced balsamic glaze over vegetables just before serving, letting it coat each piece for maximum flavor.
