Chinese Beef and Broccoli Soup

Slice the beef, against the grain, into very thin 1/8" strips. Place the meat in a medium size bowl, sprinkle with cornstarch and add the soy sauce. Toss to coat. Let the meat rest on the counter for at least 10 minutes, or up to 1 hour.
Heat 1 tablespoon of coconut oil in a large pot or dutch oven over medium high heat. When the oil is rippling hot, add half of the beef strips. Spread across the skillet in and cook without stirring for 1 minute. Stir or toss with tongs and spread across the skillet again. Cook 1 more minute. Be careful not to overcook the meat, it should be just barely cooked through and still very tender.
Carefully transfer the meat to a dish with a lid. Drain any extra liquid and add another tablespoon of coconut oil to the hot skillet. Repeat the above steps with the remaining meat. Add the last of the cooked meat and any juices to the dish and cover tightly with lid.
Add 1-2 teaspoons of coconut oil to the hot pan and add the onions, garlic, and ginger (if desired). Toss to coat the onions with oil, sprinkle lightly with salt and pepper and then allow to cook for about 5 minutes, stirring occasionally. When the onions are tender, add the broccoli and the beef stock and bring to a simmer.
Stir in the oyster sauce, taste and adjust the salt or sauce as desired. Simmer the broccoli, just until barely softened and still crisp. Remove from the heat, add the cooked meat and any juices. Stir and serve. Enjoy!
