Whisk together the teriyaki sauce by combining soy sauce, brown sugar, rice vinegar, honey, minced garlic, and grated ginger in a small saucepan. Stir until well blended and cook over medium heat.

Thicken the sauce by mixing cornstarch and water in a separate bowl until smooth. Pour this mixture into your simmering sauce, stirring constantly for about 3-5 minutes until it thickens. Once done, remove it from heat.

Heat the oil in a large skillet over medium-high heat. Let it warm up for a minute to ensure a great sear on your chicken.

Season the chicken breasts with salt and pepper, then add them to the skillet. Cook each side for about 6-7 minutes until they’re fully cooked and beautifully golden brown.

Add the pineapple to the skillet once the chicken is done. Pour the teriyaki sauce over the chicken and pineapple, making sure to coat everything generously.

Cook further for 2-3 minutes until the sauce is bubbly and thoroughly heats the pineapple through, allowing those flavors to meld together beautifully.

Garnish your dish before serving by removing it from heat and sprinkling sliced green onions and sesame seeds on top, if desired.

Serve hot over rice or with a side of steamed vegetables for a delightful meal that’s vibrant and satisfying.
