Step 1

Preheat oven to 425°F (220°C). Lightly grease a baking sheet with nonstick cooking oil spray.

Step 2

Arrange green beans on baking sheet in a single layer. Set aside.

Step 3

In a small bowl mix together olive oil, parmesan, garlic, salt and pepper. Drizzle the oil mixture over the green beans and toss to evenly coat.

Step 4

Bake for 20 minutes until vibrant and tender-crisp.

Step 5

Remove from oven and top with the mozzarella cheese. Return to oven and broil (or grill) until the cheese melts and becomes golden (about 4-5 minutes).

Step 6

Season with salt and pepper, if desired. Serve immediately.
