Simple Beef and Broccoli Stir-Fry

There are so many versions of beef and broccoli stir fry, but this is my go to one, because it's simple and quick.  Also, the freshness of the ingredients guarantees the best flavors.  Serve it on top of cooked rice and you'll get a fantastic meal.  If you have more than 2-3 people to feed, double the recipe.  Other than that, enjoy this amazing dish!
For marinade:
-1 1/2 tsp soy sauce
-1 tsp cornstarch
-1 tsp ground pepper
For stir fry sauce:
-3 Tbs oyster sauce
-2 tsp water
-2 tsp balsamic vinegar
Other ingredients:
-1 lb beef steak, cut into thin strips
-1 1/2 lbs broccoli, cleaned and cut into bite sized florets
-1 Tbs vegetable oil
-5-6 cloves garlic, minced
Combine marinade ingredients into large bowl. Mix very well.  Add the beef and stir to coat evenly.  Leave mixture on the counter until ready to use.
Meanwhile, fill a wok or large skillet halfway with water and bring to a boil.  Lower the heat and add the broccoli florets.  Cover and cook for 3 minutes.  Drain into colander and rinse with cold water to stop the cooking.  Let it drain.
While that's draining, quickly mix the stir fry sauce ingredients and set aside.
Return the wok to the stove.  Pour oil and heat up.  Add the garlic and cook for 30 seconds. Toss in the marinated beef.  Stir fry until golden brown. 
Add the broccoli and stir fry sauce.  Mix well and remove wok from stove.  Serve on top of cooked rice and sprinkle a little pepper on top.  Enjoy!
