Add the garlic and cook for about 20 seconds or until it begins to brown on the edges. Add the spinach, season with salt and pepper. Cook for about a minute until the spinach wilts (You can also use thawed, frozen spinach instead of fresh, but you will only need a small amount, since the spinach is already wilted). Set aside to cool.
<span></span>While the spinach is cooling, butterfly and pound the chicken breasts even. Top with 2-3 teaspoons of spinach and 2 slices of mozzarella or pepperjack cheese. Roll up tightly. Repeat with remaining chicken.

Heat up 1/4 cup oil in a 8 or 10 inch skillet on medium high heat, until the oil is hot and shimmering. Add the chicken to the oil and cook for about 1-2 minutes on all 4 sides, until the chicken is golden brown on all sides.
