Once the bacon is done cooking, pull it out of the pan and cut into pieces, about 1" or so each. Set aside. Keep the bacon drippings. If you don't have very much drippings, add some vegetable oil to the pan and heat it up at this point. You want maybe 3-4 tablespoons of oil. Add the sliced shitake mushrooms, chopped green onions and minced garlic. Cook until tender, maybe 3 or so minutes on high heat. Add the crab, asparagus and the bacon to the pan and stir to combine. Whip the eggs and add to the pan, stirring quickly to spread throughout the dish.
