1Preheat the broiler. Distribute the cubes of cheese evenly in a 9-inch cast-iron skillet, or in two smaller ones. Scatter with garlic, thyme, and rosemary and drizzle with olive oil. Sprinkle with salt and pepper and place the pan under the broiler for 5-6 minutes, until the cheese is melted and bubbling and starts to brown.
2Serve immediately, with crusty bread for dipping.
