Creating your Parmesan-Crusted Chicken Sheet Pan Dinner can be simple if you follow these straightforward steps:

1. Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.

2. In a shallow bowl, combine the grated Parmesan cheese, breadcrumbs, garlic powder, onion powder, oregano, basil, salt, and pepper.

3. Drizzle olive oil over the chicken breasts, coating them evenly.

4. Dredge each chicken breast in the breadcrumb mixture, pressing lightly to ensure the coating adheres well.

5. Place the coated chicken breasts on one side of the prepared baking sheet.

6. In a separate bowl, toss the mixed vegetables with a little olive oil, salt, and pepper, then spread them out on the other side of the baking sheet.

7. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F (75°C).

8. Broil for an additional 2-3 minutes for a golden-brown crust if desired.

9. Remove from the oven and let it rest for a few minutes before serving.

10. Garnish with fresh parsley if using, and enjoy!
