Carefully butterfly the chicken breasts and then pound until thin (about 1/4 inch).
Place bacon strips on a plate between paper towels and microwave for 1 minute.
In a medium sized skillet sauté chopped garlic in butter for 2 minutes over low heat. Be careful not to burn.
Add softened cream cheese and stir for 1 minute, until melted. Add baby spinach in batches and stir until wilted and blended with the cream cheese, butter, and garlic. Salt and pepper to taste.
Place thinly sliced mozzarella cheese over the flattened chicken breast then top with the spinach mixture. Roll up carefully. Wrap with 2 slices of bacon and secure with rounded toothpicks.
Sprinkle the top of the chicken roll ups with smoked paprika and bake in a shallow baking pan (cookie sheet) at 425 degrees for 30 minutes. Remove and set oven to broil and return to oven for 2-3 minutes to crisp the bacon.
You may wish to place a cooling rack for baking in your baking pan so the fat from the bacon will drain below the chicken.
