Chop up the bacon and cook it up in a wok or frying pan. Sprinkle the 7 spice over the bacon while it's cooking.
Add the chopped onion and pepper. Cook up for a bit. Add the chopped mushrooms. Then toss in the greens and bean sprouts and cover the pan to let it steam cook for about 5 or 10 minutes. Stirring occasionally.
Add a bit more spice at the end, just for good measure. Serve up!
