Preheat the oven to 180°C | 350°F. Lightly grease a baking sheet or tray with nonstick oil spray; set aside.
Cut bread in a criss-cross pattern (just over 1-inch wide), without cutting all the way through. Place bread onto prepared baking sheet/tray.
Combine butter, green onions and 1 tablespoon of parsley in a small bowl. Season with salt and pepper to your taste.
Spoon garlic butter/onion mixture into bread cracks. Arrange cheese slices and shredded cheese between the bread cuts.
Cover with foil and bake for 15 minutes. Unwrap and bake for another 10 - 15 minutes until the cheese is melted and bubbly.
