Easy Mandarin Chicken

4-6 Boneless skinless chicken breasts
1/2 c. flour
1/2 c. cornstarch
salt and pepper, to taste
2 TBS cooking oil
3 beaten eggs
pineapple tidbits
diced green pepper

Salt and pepper chicken. Cut chicken into bite-size pieces. Drop the chicken in the beaten egg mixture. Combine flour, cornstarch, salt, and pepper in a container with a lid. Remove chicken from egg and drop in the dry mixture. Put lid on and shake until each piece is well coated. Heat oil in skillet to medium heat. Brown the chicken in oil until just golden brown (don't worry about cooking through).
While the chicken is cooking, combine the following in a saucepan and heat through.
1 c. sugar
3 TBS. vinegar
1/2 c. water
4 TBS. ketchup
1 TBS soy sauce
1/2 tsp. garlic salt

(Sauce can be doubled or tripled as desired.)
Place the browned chicken in a baking dish (I use a glass 9x13). Pour the sauce over the chicken. Pour can of pineapple tidbits over chicken. Sprinkle diced green pepper over dish. Bake at 350 degrees F for 25-30 minutes or until chicken is cooked through. Sprinkle with sesame seeds when done if desired and serve over rice.
