1. Preheat oven to 425°F. Spray a 12-compartment muffin tin with cooking spray. Set aside.
2. Mix all ingredients EXCEPT cheese in a large bowl. Form the mixture into 12 2-in. balls.
3. Shred 4 oz. of the Asiago and set aside. Cut remaining Asiago into 12 cubes, approximately 1/2 in. square. Make a hole in top of each meatloaf ball and place one cheese cube inside. Reshape, covering cheese completely.
4. Bake about 25-30 min. or until done to your taste. Sprinkle the shredded Asiago over the meatloaves during last 3 min. of cooking. Remove loaves from oven and remove immediately to a warm platter. Let sit 2-3 min. before serving.
