In a bowl, add the peeled and sliced pears together with the other filling ingredients and combine so the pears are coated with the spices etc. Then add to the baking dish. Cover the pears completely with the crumble topping, but do not smooth the topping flat. Lumps and bumps will add to the crunchy texture. ** My baking dish measures 12 x 8 and 3 inches deep. Just make sure your dish is deep enough to hold all the pears and topping!
