In a large skillet, heat the vegetable oil over medium-high heat. Add the chicken pieces and cook until browned and cooked through, about 5-7 minutes.
Add the minced garlic and cook for an additional 1 minute until fragrant.
Stir in the diced bell pepper, snap peas, and pineapple. Cook for another 3-4 minutes until the vegetables are tender-crisp.
In a small bowl, whisk together the soy sauce, honey, ground ginger, and black pepper. Pour this mixture over the chicken and vegetables in the skillet.
Add the cooked rice to the skillet, stirring well to combine all the ingredients. Cook for an additional 2-3 minutes until heated through.
Remove from heat and garnish with sliced green onions before serving.
