Citrus-Tarragon Chicken Ka-bobs
These were made by Michael and Kristi for Christmas Eve dinner 2015. They were delicious. 1 chicken breast made 4-5 skewers (with 5-6 pieces of chicken on each skewer). We used about 5-6 breasts for 27 skewers. We quadrupled the marinade recipe below. We marinated for a day before hand.  

1 orange, zested, then juiced, remainder discarded
1 lemon, zested, then juiced, remainder discarded
1 lime, zested, then juiced, remainder discarded
4 cloves of garlic, minced
1/4 cup soy sauce
1/4 cup canola oil
1/2 teaspoon of salt
1/2 teaspoon freshly ground black pepper
1 lb boneless, skinless chicken breasts, cut into 1-inch cubes.

Add to pre-soaked wooden skewers along with your choice of veggies. We used:

Orange peppers
Red peppers
Yellow peppers
Zuccinni
Yellow onion

Marinate for a few hours.

Bake at 350 convection for 10 minutes (at the most).
