Sirloin tri-tip (Costco) partly frozen to make it easy to slice in small strips
2-3 tbsp. soy sauce
2 tbsp. corn starch
2 tbsp. oil
about 1 tbsp. fresh ginger (optional)
freshly ground black pepper
Slice the meat and marinate it in soy sauce, corn starch, oil, ginger, and black pepper for at least half an hour.
Wash and cut a combination of vegetables into bite-sized pieces. She did:
Broccoli
Asparagus
Red pepper
mushrooms
carrots
onion
garlic
gingerroot (optional)
Mix up the sauce. This is my version because I like a lot of sauce:
1 c. chicken broth (hot water mixed with bouillon is fine)
1-2 tbsp. oyster sauce
3 tbsp. soy sauce
1/2 tsp. sugar
2 tbsp. corn starch
1 tsp. sesame oil
Stir fry the meat in some oil and cook until barely done. Remove from pan and set aside. Stir fry the vegetables in some oil in order starting with the ones that take the longest time to cook. I start with carrots and onions. When vegetables are just about done, add the meat, then the sauce, and cook a few minutes until the sauce is thickened. Serve over rice.
