Preheat your oven to 400 degrees f. and line a large sheet pan with parchment paper.
Thoroughly wash the green beans and place them in a colander to completely drain the excess water.
To quickly trim the ends, take a handful of green beans (while picking them
place the ends in the same direction). Slice off about 1/2-inch of the stem ends and discard the ends.
Place your trimmed beans in a large bowl.
Add all the remaining ingredients, except for the mozzarella and parsley, then toss to coat each green bean with the seasonings really well.
Transfer your beans to your prepared pan and arrange them in a single layer as shown. Use a spatula to get all the leftover seasonings/oil out of the bowl and drizzle over beans.
Sprinkle evenly with mozzarella, and roast at 400 degrees f. for about 15 minutes, or until cheese is nicely melted and beans are tender-crisp.
Sprinkle with freshly chopped parsley if desired, and serve immediately.
Enjoy!
