Chop all of your vegetables while heating sesame oil ( can substitute any oil of your choice) in a large pan ( I like to use a Wok)
Cook vegetables in your pan along with half the pack of Simmer Sauce. Remove once cooked completely and set aside for later
In the same hot pan, cook your thin steak with the remaining simmer sauce until you reach your preferred temp.
Mix the vegetables back in
Serve over cooked white rice.
