I start by preheating my oven to 400°F and brushing a thin layer of olive oil over the top of the naan with a pastry brush. I place it directly on the middle rack and let it toast for 5 to 6 minutes, just until it starts turning golden. It'll get soft before it crisps up, so don't panic if it looks floppy partway through.
While the naan toasts, I mix cinnamon, nutmeg, brown sugar, and salt in a small bowl, then toss in my diced apple along with the honey and vanilla. I melt butter in a non-stick skillet over medium heat, then drop the heat to medium-low and add the apples. I let them cook covered for 5 to 8 minutes until they're soft but still hold their shape.
Once the naan is toasted, I pull it out and cut the brie into small chunks, arranging them evenly across the top. A few cracks of black pepper go on next, then it's back in the oven on a baking sheet for just 1 to 2 minutes, only long enough for the cheese to turn soft and melty.
Last, I sprinkle fresh thyme over the melted brie and start layering everything else: the cinnamon apples, a scattering of pistachios, and the pomegranate arils. If I'm feeling fancy, I finish it with a light drizzle of balsamic reduction right before serving.
