Working in batches, place the chicken pieces into the skillet and cook for a few minutes on each side to brown them. You don't want them to cook through at this point. Once the pieces are browned, place them into the prepared baking dish. Continue until all the chicken is browned.

In a small bowl, whisk together the pineapple juice, brown sugar, soy sauce, garlic, ginger and the 1 tbsp cornstarch. Pour over the chicken.

Sprinkle the diced pepper and pineapple tidbits over the top of the chicken.

Bake for 45-60 minutes. Stir every 15 minutes or so, that way everything gets an even coating of sauce. Start to check whether your chicken is done around the 45 minute mark, which is also when your sauce should start to thicken up.
