2poundsboneless skinless chicken breasts(or chicken tenders), cut into 1'' chunks
2bell peppers(any color), sliced into large chunks)
1sweet onion (or purple onion), sliced into large chunks
wooden or bamboo skewers
For the chicken marinade:
Add soy sauce, oil, sprite, garlic powder and horseradish to a large ziplock bag.
For the chicken kebabs:
Cut the chicken into 1-inch chunks and add it to the marinade. Marinate for 1-3 hours.
If using bamboo skewers, soak them in water for 30 minutes (this will help keep them from burning while cooking on the grill). Thread the chicken and chopped vegetables alternately onto the skewers, keeping a little space between each piece.
Heat grill to medium-high and grease lightly with oil.
Grill the kebabs for just a few minutes on each side (about 5 minutes), until chicken pieces are cooked through. Allow the kebabs to rest for 5 minutes before serving.
