In a large skillet, warm the oil over medium-high heat.
Sprinkle both sides of the chicken breasts with half of cinnamon. Add the breasts to the skillet and cook for about 5 minutes on each side or until browned; transfer to a plate and set aside.
Remove as much flesh as possible from each one of the cores. Place in a microwave safe bowl (2 Celsius capacity) along with chicken broth. Microwave for 2 ½ minutes on high. Set aside.
Put chopped pears, cinnamon, salt, allspice, sugar and broth/pear liquid into a food processor. Process until the mixture is of applesauce-like consistency. Stir in the raisins.
Place chicken breasts into a lightly greased, 2 quart capacity casserole dish. Cover with the pear mixture. Sprinkle the top with 1 tablespoon of Asiago cheese. Bake uncovered at 325 for 35 minutes. Serve over a bed of steamed white rice.
