In a large skillet, heat the olive oil over medium heat. Add the chicken pieces and season with salt and pepper. Cook until the chicken is browned and cooked through, about 5-7 minutes.
Add the diced red bell pepper and cook for an additional 3-4 minutes until the pepper is tender.
Stir in the pineapple chunks, frozen peas, soy sauce, honey, garlic powder, and ginger powder. Cook for another 2-3 minutes until everything is heated through.
Add the cooked rice to the skillet and mix well to combine all ingredients. Cook for an additional 2-3 minutes, stirring occasionally.
Remove from heat and stir in the sliced green onions. Garnish with chopped cilantro if desired.
