Preheat oven to 400 degrees. Coat a medium baking dish with cooking spray. Set aside.
Place each chicken breast between two sheets of plastic wrap or wax paper. Using a meat mallet, tenderize until chicken breast is approximately 1/4 inch thick.
In a small bowl, combine garlic, chopped spinach, garlic and currants. Toss well.
Place one chicken breast onto a cutting board or other clean work surface. Divide spinach mixture evenly among chicken breasts. Roll up lengthwise, folding in edges, and place seam side down into a casserole dish lightly coated with cooking spray.
Season chicken to taste with fine sea salt and freshly ground black pepper.
Bake, uncovered, for 25-30 minutes, or until juices run clean.
While stuffed chicken cooks, prepare the apple gravy. In a medium saucepan, combine chicken broth, apple juice cornstarch, thyme and apples. Bring to a low simmer. Continue apple gravy over low heat until stuffed chicken is complete. Before serving, add butter.
Slice stuffed chicken and smother with sweet apple gravy.

**Note: To remove as much liquid as possible from spinach, squeeze thawed spinach in paper towels until little to no moisture remains. The volume will decrease significantly, this is normal.
