Season the Chicken: In a small bowl, combine the ground ginger, black pepper, and a pinch of salt. Toss the diced chicken pieces with this seasoning mixture until evenly coated, about 1 minute.
Sear the Chicken: Heat 2 tablespoons of olive oil in a large skillet or wok over medium-high heat for about 1 minute. Add the seasoned chicken and cook without stirring for 3 to 4 minutes to develop a golden crust on one side, then stir and cook for another 3 to 4 minutes until cooked through and no longer pink inside. Remove the chicken to a clean plate.
Create the Glaze: In the same skillet, whisk together the teriyaki sauce, honey, and Asian chili garlic sauce over medium heat, stirring constantly until combined and fragrant, about 1 to 2 minutes.
Cook the Vegetables: Add the sugar snap peas and red bell pepper to the glaze in the skillet, stirring frequently over medium-high heat for 2 to 3 minutes until they soften slightly but remain crisp.
Add the Pineapple: Gently fold in the fresh pineapple pieces and cook for 1 minute, allowing the glaze to coat everything evenly.
Return the Chicken: Add the cooked chicken back to the skillet, stirring gently to combine with the vegetables and glaze. Cook for 1 to 2 minutes, tossing occasionally, until everything is heated through and glossy.
Plate the Dish: Divide the pineapple teriyaki chicken mixture evenly among serving bowls or plates.
Drizzle the Oil: Lightly drizzle the remaining 2 tablespoons of olive oil over the top for extra richness and shine.
Garnish: Top with sliced green onions and sesame seeds if desired, adding both flavor and visual appeal.
