Mix ranch seasoning with a little bit of olive oil. This should create a thick rub, not a thin sauce.
Gently massage the ranch mixture into the chicken breasts and let sit to marinade about 20 minutes.
Preheat grill and grill chicken until fully cooked.
If you'd like a side of ranch vegetables, sprinkle a little ranch seasoning directly onto chopped vegetables and cook in the STOK Veggie insert.
