Heat the Oil: Begin by heating olive or sesame oil in a large pan over medium heat. Once hot, add the chicken breast pieces and cook until browned and fully cooked through, about 6-8 minutes. Then, set it aside on a plate.

Sauté the Garlic: In the same pan, add the minced garlic and sauté for about 30 seconds until it becomes fragrant.

Create the Sauce: Pour in the soy sauce, pineapple juice, honey, and vinegar, stirring well to combine. Bring this mixture to a simmer for about 2 minutes.

Thicken the Sauce: Stir in the cornstarch mixed with water, to thicken the sauce to a glossy finish. Cook for an additional 2-3 minutes until thickened.

Combine with Chicken: Add the sautéed chicken back to the pan, along with the pineapple chunks and diced red bell pepper, stirring to coat everything.

Fold in the Rice: Gently fold in the cooked rice, stirring until warmed through and evenly mixed.

Garnish and Serve: Remove from heat and garnish the dish with chopped green onions and a sprinkle of sesame seeds. Serve hot.
