Make the most of the short asparagus season in early summer. Roasting the asparagus is a healthier alternative to drenching them in butter.
For a smoky flavour, cook the asparagus on the barbecue. Brush the spears with 2 teaspoons of the oil and place them on the rack above hot coals. Using tongs, turn them at least once and cook until they have softened and browned slightly.
