Preheat the oven to 350 degrees Fahrenheit. Cut 1½ pounds boneless, skinless chicken breasts into bite-sized pieces and season with ½ teaspoon salt and ¼ teaspoon black pepper.
Add 1½ cups cornstarch to one bowl and 3 large beaten eggs to another bowl. Dip each chicken piece into the cornstarch, then coat it in the egg mixture.
Heat ½ cup canola oil in a large skillet over medium-high heat and cook the chicken until browned. Place the chicken in a 9 x 13 greased baking dish.
Mix ⅔ cup granulated sugar, ½ cup lemon juice, 2 tablespoons soy sauce, 3 tablespoons white vinegar, 1 tablespoon lemon zest, ¼ teaspoon garlic salt, and 1 teaspoon cornstarch in a medium-sized bowl.
Pour the sauce over the chicken and bake for 45 minutes. Stir the chicken every 15 minutes so that it is coated in the sauce.
Serve over rice and enjoy!

Notes
Leftover Instructions
In the refrigerator: Store leftover chicken in an airtight container for up to 3 days.
To reheat: Warm the chicken in a skillet over medium-low heat or in a 350°F oven until heated through. The microwave will work, but the coating will be softer.
In the freezer: Freeze the cooled chicken in an airtight container for up to 2 months. Thaw it overnight in the refrigerator before reheating.
