Toss all the ingredients together (except the whole orange). Marinate for 30 minute.
Alternate the chicken and poblano chile pieces on wooden skewers ( if wooden -- soak in water for 30 minutes) season with salt and freshly ground pepper. Place the skewers on a preheated grill over moderate flame and cook for 3 minutes on each side or until the chicken is cooked.
Season once more with salt and pepper and squeeze a fresh orange over the cooked chicken kabobs.
