Double Hearty Haloumi & Caramelised Onion Burger

• Meanwhile, thinly slice brown onion. • Thinly slice tomato. • Finely shred baby cos lettuce (see ingredients). • Cut haloumi into 1cm-thick slices.

• In a large frying pan, heat a drizzle of olive oil over medium heat. Cook onion, stirring regularly, until softened, 5-6 minutes. • Add the balsamic vinegar(for the onion), brown sugar and a splash of water. Mix well. Cook until dark and sticky, 3-5 minutes. • Transfer to a small bowl.

• Wash and dry frying pan, then return to medium-high heat with a drizzle of olive oil. • When oil is hot, cook haloumi, in batches, until golden, 1-2 minutes each side.

• Meanwhile, halve bake-at-home burger buns and bake directly on a wire rack in the oven, until heated through, 2-3 minutes. • Reserve a handful of the cos lettuce for the burgers, then place the rest in a medium bowl. • Add the balsamic vinegar(for the salad) and a drizzle of olive oil. Toss to coat. Season to taste.
