After the potatoes cook through, peel off the skin, cut into 4/ 5 thin slice, and lay it on a baking tray. On top of the potatoes, put the garlic sauce, dice green bell pepper, chopped onion, broccoli and mozzarella. Drizzle it with olive oil and season it with black pepper. Put it into the preheated oven in 180c for about 12-15 minutes or until the cheese is melted.
