Slice the steak against the grain, in bite sized strips. Place in a mixing bowl.
In a small bowl, whisk together your coconut oil, soy sauce, minced garlic, and apple cider vinegar and mix well. Pour over the steak to ensure the sauce covers all the meat.
Heat a non-stick pan with one tablespoon of sesame oil. When hot, add your marinated steak and half the sauce it is in. Sear for 5 minutes, turning halfway through, for the steak to cook both sides.
Add the second tablespoon of sesame oil and add the broccoli and the rest of the sauce. Cook for 10 minutes, until the broccoli is tender. Reduce heat to low and continue simmering until the broccoli is cooked to your desired texture.
