Preheat the oven to 325 degrees Fahrenheit and grease a 13 x 9 x 2-inch baking dish. Cut 3-4 boneless skinless chicken breasts into bite-sized pieces and season with salt and pepper.
Add 1¼ cups cornstarch to a large Ziploc bag, along with the cut chicken pieces. Close the bag and shake to coat the chicken well.
In a small bowl, whisk together 3 eggs. Dip each coated chicken piece into the beaten eggs to coat the chicken, then shake off any excess egg. Set aside on a plate while you coat the remaining chicken.
Heat ¼ cup canola oil in a large skillet over medium-high heat. Cook the chicken until browned. Place the chicken in the prepared baking dish.
In a medium bowl, whisk ⅔ cup brown sugar, ⅔ cup orange juice, ¼ cup low-sodium soy sauce, 2 teaspoons sriracha, 3 tablespoons white vinegar, 3 tablespoons apple cider vinegar, 1 teaspoon garlic salt, 1 tablespoon grated orange peel, and 1 tablespoon cornstarch.
Pour the sauce over the chicken and bake for 1 hour, stirring the chicken every 15 minutes to coat the chicken in the sauce. Serve over rice and enjoy!
