Ingredients

• 2 medium, sliced 1/2-inch thick Zucchini
• 2 medium, sliced 1/2-inch thick Yellow squash
• 1, cut into 1-inch strips Red bell pepper
• 1 medium, sliced 1/2-inch thick Red onion
• 3 tbsp Olive oil
• 1 tsp Dried oregano
• 1/2 tsp Dried thyme
• 3/4 tsp Salt
• 1/2 tsp Black pepper

Instructions

1. Step 1: Preheat oven to 425°F; arrange 2 sliced zucchini, 2 sliced yellow squash, 1 cut red bell pepper, and 1 sliced red onion on a large baking sheet.
2. Step 2: Drizzle with 3 tbsp olive oil, then sprinkle with 1 tsp dried oregano, 1/2 tsp dried thyme, 3/4 tsp salt, and 1/2 tsp black pepper; toss gently until vegetables are evenly coated.
3. Step 3: Roast for 25 minutes, stirring once halfway through, until vegetables are tender-crisp with deep golden-brown edges and aromatic.
