Being from Alaska we grill EVERYTHING and at EVERYTIME: Sunshine, Rain, Snow, we grill. Found this recipe on Betty Crocker.com. It's fancier than what we do back home, but they love the recipe when they use it.
Soak the skewers in water for 30 mins. In shallow glass or plastic dish or resealable food-storage plastic bag, mix onion, garlic, paprika, pepper flakes, cumin, salt, 2 tablespoons of the olive oil and lemon juice. Add chicken; turning to coat with marinade. Cover dish or seal bag; refrigerate, turning chicken occasionally, at least 1 hour to marinate.
Heat gas or charcoal grill. Thread chicken and bell pepper pieces on skewers.
Place kabobs on grill over medium heat. Cook 9 to 11 minutes, turning occasionally; brushing with remaining 2 tablespoons oil, until chicken is no longer pink in center.
