Pre-heat oven to 400°F.
In a medium size mixing bowl, place green beans, enough oil to coat beans, pinch of salt and pepper.
Mix until everything is covered.
On a cookie sheet, lined with parchment paper, lay green beans, and sprinkle a healthy amount of cheese on top.
Bake for about 15 – 20 minutes or until green beans are crisp on the outside and tender on the inside.
