1. Preheat the Oven: Preheat your oven to 400°F (200°C).

2. Prepare the Baking Sheet: Line a large baking sheet with parchment paper or lightly grease it with cooking spray.

3. Season the Chicken: Place the chicken breasts on the baking sheet. Drizzle 1 tablespoon of olive oil over the chicken and season with salt, pepper, garlic powder, onion powder, and Italian seasoning (if using). Rub the seasonings evenly over the chicken.

4. Add the Vegetables: In a large bowl, combine the mixed vegetables with the remaining tablespoon of olive oil, salt, and pepper. Toss to coat the vegetables evenly. Spread the vegetables around the chicken on the baking sheet.

5. Bake: Bake in the preheated oven for about 25-30 minutes, or until the chicken is cooked through (internal temperature should reach 165°F/75°C) and the vegetables are tender.

6. Serve: Remove from the oven and let it rest for a few minutes. Serve the chicken and veggies warm, with lemon wedges on the side if desired.

Tips:

• You can customize the vegetables based on your preferences or what you have on hand.
• For extra flavor, marinate the chicken in your favorite dressing for a few hours before cooking.
• Serve it with rice, quinoa, or a simple salad for a complete meal.
