Place beef broth in a medium pot and bring to a gentle boil.
Add the steak to the pot. The steak should be covered by the broth. If it's not, add water.
Place the broccoli on top of the steaks and reduce heat to medium.
Cover and reduce heat to medium low and simmer for 15 minutes or until the steak is cooked thoroughly and the broccoli is tender.
Remove from heat and mash the beef and broccoli with an immersion blender until you get your desired texture.
