Preheat oven 375°. Place about 10 oz fresh spinach leaves in glass bowl and microwave on high for 3 minutes stirring every minute. Stir in 1/2 C sour cream, 1 C shredded cheese of your choice (mozzarella, monterrey jack, feta, cheddar, etc.), and 4 cloves minced garlic.
Pound out 8 skinless, boneless chicken thighs (I had to de-bone & de-skin mine) to approx. 1/2 inch thickness. Place several tablespoons of spinach mixture onto each chicken piece then roll up tightly. Either tie tightly with kitchen string or hold with a toothpick.
Place in lightly greased baking pan. Sprinkle with salt and pepper. Cook at 375° for 35 minutes then increase heat to 500° or under broiler for 5-10 minutes to brown.
