Combine the soy sauce, balsamic vinegar, Worcestershire sauce, brown sugar, ginger and chilli paste (or fresh minced ginger and finely diced chilli) in a small bowl.
Heat 1 tbsp of toasted sesame oil in a large frying pan or wok. Fry the onion for 5 minutes until softened. Stir in the garlic and fry for a minute more.
Add the frozen mince, stirring until it breaks down and starts to brown.
Add the eggplant and mushrooms and cook over high heat for 5 minutes, adding more oil if needed.
Add the sauce and continue to cook until the aubergine is softened, another 5-10 minutes. If using noodles, stir them in a few minutes before the end.
Top with toasted sesame seeds, chopped chives, sprouted seeds and as much spicy chilli oil as you can take.
