Beef & Onion Stir Fry

 

1 pound beef

1 T. soy sauce

1 T. oyster sauce

1 T. rice vinegar

1 T. sesame oil

1 T. cornstarch

1/2 tsp. sugar

1 T. cooking oil

1 medium onion

 

Slice beef and onions. Combine soy sauce, oyster sauce, rice vinegar, sesame oil, cornstarch, salt, and sugar in a large bowl or zip lock bag. If you are about to cook it, let it marinade at the very least 15-30 minutes. If you are making this ahead, cover and refrigerate for 30 minutes before cooking. In a large nonstick skillet, add 1 T. of oil over medium-high heat. Add the beef, and stir fry until mostly browned, and then add the sliced onions. Stir fry for about 4 minutes or until onions soften.
