Heat olive oil in a large skillet over medium-high heat.
Season chicken with salt and pepper then add to the skillet.
Sear outside until a nice golden crust forms.
Remove chicken from pan, add in bell peppers and saute for 3-5 minutes until tender, remove from pan.
Add sauce ingredients to pan, and bring to a simmer, add chicken back in, and cook on medium-low heat, letting sauce reduce while chicken cooks through.
Add peppers and pineapple to pan, and cook a few minutes more, until sauce is thick, sticky, and glossy, and peppers are tender.
Serve over cooked white rice.
