2 garlic cloves, minced
1 1/2 teaspoons minced serrano chilli with seeds
80ml soy sauce
60ml (packed) dark brown sugar
45ml unseasoned rice vinegar
45ml water
1 tablespoon Asian sesame oil

How to make Grilled Halibut, Aubergine, and Baby Bok Choy with Korean Barbecue Sauce
Heat 1 tablespoon olive oil in heavy small saucepan over medium heat. Add garlic and chilli; sauté until fragrant and light golden, about 3 minutes. Add soy sauce, brown sugar, vinegar, and 3 tablespoons water and bring to boil, stirring until sugar dissolves. Reduce heat to medium and simmer until mixture is reduced to 180ml , about 5 minutes (sauce will be thin). Remove barbecue sauce from heat; whisk in sesame oil. Transfer 60ml barbecue sauce to small bowl and reserve for serving.
Prepare barbecue (medium heat). Combine bok choy and aubergine halves in large bowl. Drizzle 2 tablespoons olive oil over and toss to coat. Sprinkle with salt and pepper. Brush fish with remaining 1 tablespoon olive oil; sprinkle with salt and pepper. Grill vegetables and fish until vegetables are tender and slightly charred and fish is just opaque in centre, turning occasionally and brushing with sauce, about 10 minutes total for vegetables and 7 minutes total for fish. Transfer vegetables and fish to plates; sprinkle with spring onions. Drizzle with reserved sauce and serve.
