Ingredients for 1 stuffed chicken breast:
Set grill to 275F (or oven to 300F).
Using a sharp knife, make a lengthwise cut from the thickest side of a chicken breast to within 1/2 inch of the opposite side. Open chicken so it lies flat and resembles a butterfly or heart.
Season the chicken breast and rub in the seasonings.
Open the chicken breast and add the veggies and cheese.Tightly pack in the ingredients so the chicken can fold close.
Place the stuffed breast on the grill, or baking sheet for the oven, and bake for about 25 minutes. About halfway through the cooking, you can carefully flip the chicken breast over to create grill marks on the opposite side but be careful not to spill the stuffing. You will know the chicken breast is done when the flesh is no longer pink and the juices run clear.
Enjoy.
