Preheat the oven to 325 ℉. Cut the chicken breasts into 1-inch pieces. Season with salt and pepper to taste. Place the cornstarch in a gallon-sized Ziplock bag. Place the chicken pieces into the bag with the cornstarch and seal, tossing to coat the chicken.
Whisk the eggs together in a shallow pie plate.
Meanwhile, heat the oil in a large skillet over medium heat until very hot. Dip the cornstarch-coated chicken pieces in the egg and place them carefully in a single layer in the hot skillet.
Cook for 20 to 30 seconds on each side until the crust is golden. (The chicken will finish cooking in the oven.)
Place the chicken pieces in a single layer in a 9x13-inch baking dish and repeat with the remaining chicken pieces.
Sweet and Sour Sauce
Mix the sweet and sour sauce ingredients together in a medium bowl and pour evenly over the chicken.
Bake the chicken, uncovered, for 40 minutes, tossing the chicken once at the halfway mark. Serve over warm rice and enjoy!
