Warm up the olive oil in a cast iron skillet along with the garlic.

Add the chicken and cook until well done.

While the chicken is cooking in a medium sized saucepan, add the pineapple chunks with juice, pepper, onion, 1 1/2 Cups water, sugar, and vinegar.  Whisk well then add the soy sauce and ketchup.

Whisk well until it reaches a boil.

Once boiling, whisk in the cornstarch and water and stir until it's thickened.
