Gouda Spinach Hasselback Chicken

"This super simple Hasselback Chicken is made flavorful with Gouda cheese and fresh baby spinach. The spinach helps keep the chicken moist while the Gouda and the herbs infuse flavor. I love to serve this dish with Green Beans with Toasted Almonds and Garlic and Roasted Rosemary Potatoes. It is simply chicken breasts that have slices about 1/2 inch apart but not all the way through creating pockets that you can stuff with spinach, sun-dried tomatoes, sliced bell peppers, mushrooms, zucchini, onions or various kinds of cheese.
