Combine confectioners' sugar, strawberries and lemon juice in bowl of a food processor or blender. Process until chunky. (This will yield about 2 cups strawberry sauce.)
Toast waffles according to package directions. Let waffles cool slightly and cut each into quarters.
Place a scoop of ice cream in center of a bowl or plate. Spoon a small amount of strawberry sauce over and around ice cream. Stick 4 waffle wedges into each serving of ice cream. Top with dollops of whipped cream or other whipped topping, if desired. Serve with remaining strawberry sauce.
