Medium rare beef, mushrooms, and broccoli in beef gravy are perfect companions. This recipe uses some of the rare beef roast and gravy, morphed into a spicy stir fry sauce. If you add the roast right at the end, then each strip of beef is like a mini steak cooked on the outside but still soft and medium rare on the inside. I exert my right as chef with the broccoli. I do not like it stir-fried, so instead, I steam it, stop the cooking, and add it at the end with the beef and sauce. Make sure you cut everything up ahead of time. It just takes the stress out of cooking.
