Heat the olive oil in a wok or a large frying pan with high sides over medium-high heat. Add the pork and cook, stirring occasionally, until the pork is nicely browned on all sides, around 3-4 minutes.
2 Tablespoons extra virgin olive oil, 1.5 lbs. pork tenderloin
Add bell pepper, ginger, cashews and garlic powder. Stir fry the veggies until they become crisp-tender, around 2-3 minutes.
1 medium red bell pepper, ½ teaspoon ground ginger, ⅓ cup raw cashews, ½ teaspoon garlic powder
Add the bok choy, sesame oil, and soy sauce. Continue to stir fry until the bok choy wilts and the other ingredients are coated, approximately 1-2 minutes.
1 baby Bok choy, 2 Tablespoons soy sauce, 3 Tablespoons toasted sesame oil
Remove from heat and transfer to individual serving plates. Garnish with toasted sesame seeds or green onions if desired, and serve immediately.
2 Tablespoons toasted sesame seeds, 1 green onion
