Cheesy Baked Garlic Green Beans

Instructions:

First, preheat the oven to 425°F (220°C). Spray the baking tray with a little cooking oil spray.
Arrange the green beans on the tray in a single layer. Leave it aside.
Take a small bowl, and mix Parmesan cheese, olive oil, garlic, salt, and pepper. Pour the mixture over the green beans and stir evenly.
Put it in the oven for 20 minutes, until cooked.
Then remove from the oven and top with mozzarella, then return to the oven and roast until the cheese melts and turns golden (about 4-5 minutes).
