Cut the chicken into bite-sized pieces and season with salt, pepper, and a little soy sauce.
Coat the chicken pieces with flour and cornstarch until evenly covered.
Heat oil in a pan and fry the chicken until golden brown and crispy. Drain excess oil.
In a separate pan, sauté minced garlic and ginger until fragrant.
Add fresh orange juice, orange zest, soy sauce, sugar, vinegar, and a little cornstarch mixed with water.
Simmer the sauce until it becomes thick, glossy, and flavorful.
Add the crispy chicken and toss until every piece is coated with the orange sauce.
Garnish with orange zest and sesame seeds. Serve immediately with rice or noodles.
