Cut pears into 1/4-inch thick slices; set aside. Spread 1 teaspoon peanut butter on each slice of bread, one side only. Place pears on peanut butter side of 4 slices. Put 2 slices of bread together to make a sandwich with peanut butter and pears for the filling; repeat with remaining slices. In medium shallow bowl, combine eggs, milk, honey and cinnamon; whisk or stir with fork until blended. Dip sandwiches into egg mixture, evenly coating both sides. In large skillet, melt butter over medium heat. Cook sandwiches 1 to 2 minutes on each side until golden brown. Serve hot with honey or syrup.
