Easy Honey Haloumi & Harissa-Aioli Tacos

• In a small microwave-safe bowl, combine onion, the white wine vinegar and a good pinch of sugar and salt. • Microwave onion in 30 second bursts, until softened.

• Drain haloumi and pat dry. Cut haloumi into 1cm-thick slices. • In a large frying pan, heat a drizzle of olive oil over medium-high heat. Cook haloumi until golden brown, 1-2 minutes each side. • Remove from heat, then add the honey, turning to coat.
