Trim sirloin beef removing any excess fat. Cut beef into thin strips, about ¼ inch thick.
Place beef strips in a large ziplock baggie. Set aside while you make the marinade.
In a mixing bowl whisk together soy sauce, water, cornstarch, ground ginger, brown sugar, minced garlic, rice vinegar, honey and sesame oil until well combined.
Pour marinade into the baggie with the strips of beef.
Seal bag squeezing out excess air.
Marinate beef in the refrigerator for 8 hours or overnight.
Place a strainer over a bowl and pour beef and marinade into the strainer allowing marinade to drain off into the bowl.
Pour marinade in a sauce pan and bring to a boil over medium high heat. Boil for 3-4 minutes stirring occasionally until the sauce thickens slightly. Remove from heat.
In a large skillet heat olive oil over medium high heat.
When the oil is hot add drained marinated beef to the pan and cook stirring occasionally, about 3 minutes.
Add the cooked marinade to the pan and stir to coat the beef strips.
Add asparagus or broccoli to the pan and continue to cook until vegetables are crisp tender, about 2-3 minutes.
Serve over a bed of cooked white rice and top each serving with a sprinkle of sesame seeds.
