A beautifully plated symphony of shades of brown and green. The delicate, fluffy Japanese omelette is tenderly folded over a mixture of golden caramelized onion and vibrant avocado cubes. Sprinkles of finely chopped spring onions on the side of the omelette offer a burst of fresh green. Beside it, a bowl of deep-brown roasted onion miso soup showcases slices of roasted onion swirling around, adorned with a sprig of parsley.
