This open-faced tuna melt is one of those simple, no-fuss meals that always hits. Crispy sourdough with melty cheddar straight from the oven, topped with fresh greens and a creamy, crunchy tuna mix. It’s warm, fresh, and comes together with basic ingredients you probably already have, easy to throw together, but still feels like a proper meal.

Makes 1

Ingredients

  • 2 slices sourdough bread
  • 2 slices cheddar cheese
  • 1 can tuna drained
  • 1 heaping tbsp mayonnaise
  • 1 small pickle diced
  • 1 tbsp red onion finely diced
  • Salt and pepper to taste
  • 1 handful mixed greens or arugula

Instructions

  • Prep the tuna: In a bowl, mix together the tuna, mayonnaise, diced cucumber, and red onion. Season with salt and pepper to taste. Set aside.
  • Toast the base: Preheat your oven to 400°F (200°C). Place the sourdough slices on a baking tray, top each with a slice of cheddar, and bake until the bread is crisp and the cheese is melted and bubbly.
  • Assemble: Remove from the oven and top each slice with a handful of mixed greens or spinach. Spoon the tuna mixture generously over top.
  • Serve: Serve right away while the bread is warm and the cheese is still melty.
