Suggestions - start viewing good quality meat imported from US/AUS as a treat, not as a staple food. Eat more tofu. Eat more fish, however many wet markets sell juvenile fish these days so there you have a potential ethical dilemma relating to overfishing. Use sites lime meatmarket.hk mentioned above (quality is great but you certainly pay for it). Learn to cook like the locals using poor quality Guangzhou pork and chicken but for them it's not about the quality of the ingredient but what you can do with the ingredient. Cooking at home in HK can be a real pain the arse, but you’ll find the solutions that work for you over time. Good luck.
