Step 1

. In a large mixing bowl, add cubed pork, salt, Shaoxing wine (if using), soy sauce, and egg. Stir well and press the marinade to coat evenly. Let the marinated pork rest for 5 minutes to soak in all the flavour.

Step 2

. Prepare a shallow bowl with cornstarch (or flour) and dip the marinated pork to coat evenly on all sides. Set aside on a plate.

Step 3

. You can deep fry, air fry, or bake the pork.

Step 4

To air fry: Place the battered pork in a single layer in the air fryer basket and lightly spray with cooking spray oil to coat evenly. Cook the pork (in 2 batches) at 350F for 10-12 minutes until golden brown and cooked through. Shake the basket halfway to cook the pork evenly. Set aside on a plate.

Step 5

To bake in the oven: Place the battered pork in a single layer on a parchment lined baking sheet and lightly spray with cooking spray oil. Bake in a 400F preheated oven for 15 minutes until golden brown. Set aside on a plate after baking.

Step 6

In a small mixing bowl, whisk together all the sauce ingredients including ketchup, soy sauce (or oyster sauce), water (or chicken broth), sugar, vinegar, cornstarch, and salt until smooth. Set the aside.

Step 7

. Heat oil in a large skillet over medium-high heat until the hot oil sizzles, about 1 minute. Add bell peppers, onion, and pineapple and sauté for 1 minute.

Step 8

. Stir in the sauce mixture and let it simmer over medium heat for 3-4 minutes until thickened to a desired consistency, stirring constantly.

Step 9

. Add the cooked pork and toss well to coat, about 1 minute.

Step 10

. Garnish with sesame seeds and green onions and serve warm with a bowl of steamed rice or fried rice.
