Heat half of the oil in a skillet over medium-high heat. When hot, add the cubed pork and the salt and pepper. Stir fry for 5-6 min until almost fully cooked. Remove pork and set aside.

Put remaining oil into the skillet and add the frozen vegetables. Stir fry 4-5 minutes or until crisp but warmed through.

Return pork to skillet, stir.

Pour in stir-fry sauce and mix until it is well distributed.

Reduce heat to low and simmer until pork is fully cooked.

Serve.
