Step 1

Mix all the sauce ingredients in a small bowl and set aside.

Step 2

Combine chicken pieces, vegetable oil, and salt in a big bowl. Mix well and let marinate for 10 to 20 minutes.

Step 3

Add the beaten egg into the bowl with the chicken. Stir to mix well. Add cornstarch. Stir to coat chicken, until it forms an uneven coating with a little dry cornstarch left unattached.

Step 4

Heat oil in a heavy duty skillet until hot, until it just starts to smoke. Add chicken all at once and spread out into a single layer in the skillet. Separate chicken pieces with a pair of tongs or chopsticks.

Step 5

Cook without touching the chicken for 2 to 3 minutes, or until the bottom turns golden. Flip to brown the other side, 2 to 3 minutes. Transfer chicken to a big plate and remove the pan from the stove. Let cool for 2 to 3 minutes.

Step 6

Place the pan back onto the stove and turn to medium heat. You should still have 1 to 2 tablespoons oil in the pan. Add garlic. Cook and stir a few times until it releases its fragrance.

Step 7

Stir the sauce again to dissolve the cornstarch completely. Pour into the pan. Stir and cook until it thickens, when you can draw a line on the bottom with a spatula without the sauce running back immediately.

Step 8

Add back the chicken pieces, white onion, and bell peppers. (*Footnote Stir to coat chicken with sauce, 30 seconds. Transfer everything to a plate immediately.

Step 9

Serve hot as main over steamed rice.
