Prepare grill & cover to build an intense heat. Remove nectarine pits & slice each one into 6 slices. Combine sugar, zest, lemon juice in a small bowl. Place 6 nectarine slices on a skewer & place on grill. Cook 5 minutes, turn & baste with glaze. Cook & baste for another 7 minutes. When fruit is just about done, toast cake slices on a cooler part of the grill, turning once. Serve toasted cake with grilled nectarines & handfuls of blueberries. "Vegetarian Times" July, 1993
