Tarragon mayo adds an instant kick to this otherwise ordinary sandwich, making it a quick and delicious weeknight meal.

Ingredients

  • 2 tsp canola oil, divided

  • 1 red onion, sliced into ¼-in. rounds, keeping rings intact

  • 500 g haddock, or other firm white fish, in 4 pieces

  • 3/4 tsp salt, divided

  • 4 burger buns

  • 4 butter lettuce leaves

  • 1 tomato, sliced

Tarragon Mayo

  • ¼ cup mayonnaise

  • ¼ cup plain Greek yogurt

  • 1 ½ tsp finely chopped tarragon

  • 1 tsp lemon juice

Instructions

  • Preheat barbecue to medium-high. Place a large oven-proof frying pan or cast iron pan on one side of grates.

  • Stir mayo with yogurt, tarragon and lemon juice in a small bowl. Season with pepper.

  • Brush 1 tsp oil over onion rounds. Pat fish fillets dry with paper towels, then sprinkle with ½ tsp salt. Season with pepper. Arrange onion over grill grates. Add remaining 1 tsp oil to preheated pan, then fillets. Cook onion and fish, with lid closed, until onions are tender and fish flakes easily with a fork, 2 to 4 min per side.

  • Transfer onion and fish to a platter. Sprinkle onion with remaining ¼ tsp salt.

  • Serve fish on buns spread with tarragon mayo and top with grilled onions, lettuce and tomato.
