Grilled Chicken Fajitas

I have seen several recipes for gilled chicken fajitas around the web.  This is my own take on it and we love them.

3-5 Boneless Skinless Chicken Breasts
3 Bell Peppers (we used red, orange and yellow)
2 Onions
1 package Fajita Seasoning
1 cup Olive Oil
Tortillas
Mexican Fixings: Sour Cream, Guac, Cheese, etc.

Whisk together olive oil and fajita seasoning.  Place chicken breasts in ziplock bag and pour the fajita marinade over the chicken.  Place in refrigerator for 3 to 6 hours.

Cut bell peppers and onions in long strips.  Make a foil pack with the bell peppers and onion inside.  Remove chicken from the refrigerator and place on the hot grill.  Place the foil packet on the grill as well.  Cook the chicken on each side for 6 to 7 minutes or until chicken is fully cooked.  Check the peppers to make sure they are not getting over done, remove from grill when they are cooked and slightly charred. Remove the chicken breasts from the grill and slice into strips, toss with peppers and onions and serve family style on a platter.
