Step 1

Combine all of the sauce ingredients and whisk very well (or shake in a jar with a lid) until all bits of cornstarch are mixed in.

Step 2

Stir together chicken and salt. Sprinkle flour over the chicken and stir until it evenly coats the chicken.

Step 3

Set all of the ingredients near the stove.

Step 4

In a wok or large skillet, heat the oil over medium-high heat.

Step 5

When the oil begins to shimmer, add the chicken. Let the chicken cook without stirring until it is golden brown on the bottom, about 2 minutes. Turn the chicken and continue cooking until it is just cooked through, 2 to 3 minutes more. Transfer chicken to a plate or bowl.

Step 6

If the wok looks dry, add some additional cooking oil. To the heated oil, add the yellow onion and ginger and cook, stirring often, until the onion starts to soften, 2 to 3 minutes more.

Step 7

Pour the sauce over the onions. Bring to a simmer. Let the sauce simmer for 1 minute.

Step 8

Stir in the green onions and chicken. Simmer everything together for 1 minute to coat in sauce.

Step 9

Serve over rice.
