1. In a large pan or wok, over medium heat cooking oil. Add chicken breast and season with a little salt and pepper. Cook through while stirring a few times until no longer pink.
2. Add chopped red pepper and pineapple chunks to the pan. Cook for about 5 minutes, stirring a few times.
3. Add ginger and garlic. Stir and cook for a couple minutes.
4. Add the pineapple juice, soy sauce, chicken broth, hoisin and brown sugar. Stir so everything is combined. Allow to simmer for about 10 minutes.
5. Next, add the cornstarch and water mixture. Combine well with the sauce and bring to a slight boil. Reduce the heat and simmer for a couple minutes. The sauce should thicken up some. 
6. Serve over rice and sprinkle sesame seeds over top along with some chopped green onions. Enjoy!

To Cook in the Oven: Combine all the recipe ingredients and pour them into a baking dish (9″ is fine). Cook uncovered for about 30-35 minutes. Before serving, stir the contents of the dish and allow to sit for about 5 minutes. Serve over rice and garnish with sesame seeds and chopped green onions. 

To Cook in a slow cooker/crock pot: Season the chicken, then add it along with the red pepper, pineapple chunks, garlic, and ginger to the slow cooker. Mix the pineapple juice, soy sauce, chicken broth, hoisin, and brown sugar, then pour it over the ingredients. Cook on low for 4-6 hours (or high for 2-3 hours). About 30 minutes before serving, stir in the cornstarch mixture to thicken the sauce. Serve as directed in the original recipe.

To Cook in an Instant Pot: Using the sauté function, brown the chicken and cook the red pepper, pineapple, garlic, and ginger for a couple of minutes. Add the sauce ingredients (pineapple juice, soy sauce, chicken broth, hoisin, and brown sugar). Pressure cook on high for 5 minutes. After releasing the pressure, thicken the sauce by stirring in the cornstarch mixture and simmering for a couple of minutes. Serve as in the original recipe.

 To prepare in Advance: You can prepare your pineapple chicken in advance, but to make it as simple as possible, I’d recommend baking it according to the Oven instructions above. The ingredients can be prepared and combined up to 2 days before cooking.
