Preheat the oven to 400°F (200°C) and line a baking tray with parchment paper. Spread the grapes evenly on the tray. Drizzle with olive oil and honey. Sprinkle The Holly Tree Organic Thyme Leaves, Organic Black Pepper Powder, and Organic Chili Flakes over the grapes. Toss gently to coat. Roast for 18–20 minutes, or until the grapes soften, blister, and begin to caramelize. Transfer the warm burrata to the center of a serving plate. Spoon the roasted grapes and their juices around and over the burrata. Sprinkle with the toasted walnuts. Finish with a light drizzle of honey, balsamic glaze, and an extra pinch of The Holly Tree Organic Thyme Leaves.
