Dice the chicken into 1/2 inch pieces and place in a bowl. Add in the flour, corn starch, salt, black pepper, onion powder, paprika, and ginger powder to coat the chicken.
In a deep drying pan, bring the oil to medium-high heat. Fry the chicken until golden brown. Takes about 2-3 minutes.
Meanwhile, whisk all the sauce ingredients and a bowl. Transfer to a hot skillet or frying pan and cook on low-heat, simmering until the sauce thickens up.
Transfer the fried chicken to the sauce and mix to coat well. Let the sauce and chicken simmer together for 1-2 minutes and then remove from heat.
Serve with homemade Lo Mein Noodles or White rice. Garnish with toasted sesame seeds and chopped green onions. (optional)
