Preheat your oven to 400°F (200°C).
In a large bowl, season the chicken thighs with salt, black pepper, and olive oil. Toss to coat.
Slice the red and green bell peppers and red onion. Measure out the pineapple chunks.
In a separate bowl, whisk together soy sauce, honey, minced garlic, and ground ginger. Pour half over the chicken and marinate for 10-15 minutes.
Line a sheet pan with parchment paper. Arrange marinated chicken on one side and vegetables on the other. Drizzle remaining marinade over vegetables.
Bake for 25-30 minutes until chicken reaches 165°F (75°C) and vegetables are tender. Let rest before serving.
