Sweet and Sour Chicken

I don't have a picture yet, but just imagine Chinese Take-Out Sweet and Sour Chicken, and that's what it looks like!

Chicken:

3-4 boneless skinless chicken breasts
salt and pepper
1 cup cornstarch
2 eggs, beaten
*1/4 cup canola oil
Sauce:
3/4 cup sugar
1/4 cup ketchup
1/2 cup white vinegar
1 tablespoon soy sauce
1 teaspoon garlic salt

Cut chicken breasts into chunks. Season with salt and pepper. Dip chicken in cornstarch then in egg. Fry chicken chunks in hot oil until browned but not cooked through. Place browned chicken in a single layer in a 9x13 baking dish. Mix together sauce ingredients and pour over chicken. Bake for about 45 minutes at 325 degrees turning chicken every 15 minutes. If you'd like extra sauce, mix together another batch of sauce ingredients while chicken is cooking and cook over medium heat until thickened and reduced, about 6-8 minutes.

*I've never used that amount of oil, I always use way more oil than that. Guess I better try it like that to see which way is better.
