Stuffed Chicken breasts

This is quite an elegant dish and worthy to serve to company.  It is a bit time consuming, but easy enough to make.  To make this dish you will need:
2 tablespoons butter
1/2 medium onion, chopped
1 celery stalk, chopped
1 tablespoon minced garlic
1 teaspoon minced, sage, thyme, rosemary, parsley
1/2 package of Pepperidge Farm herb stuffing crumbs
up to 1/2 cup hot water
4 boneless skinless chicken fillets
1/4 to 1/2 cup Panko breadcrumbs
Pam
1 can of Chicken gravy

1.)  In a medium saute pan over medium heat, melt the butter.  Add the onion and the celery and saute until soft (about 10 minutes).  Add the garlic and the herbs.  Stir.  Add the breadcrumbs and enough hot water to soften the crumbs and make a stuffing.  Remove from heat and allow to cool slightly.
2.)  Preheat the oven to 350 degrees.  Prepare a casserole dish by spraying it with Pam.  Between wax paper, pound or roll the chicken to thin it out.  Top with a mound of stuffing.  Roll up the chicken. 
3.)  Once you have the chicken stuffed and rolled, spray the breasts with Pam.  Sprinkle the chicken with the Panko.
4.)  Bake covered for 30 minutes.  Remove cover and bake for another 20 minutes.  Pour the chicken gravy over the top of the breasts.  Return to the oven and bake for another 20 minutes.  Enjoy!
