  • 2 cans (150g) canned Canadian albacore tuna
  • ½ cup (125 ml) plain Greek yogurt
  • ⅓ cup (33 g) carrot, grated
  • ¼ cup (42 g) red onion, minced
  • 1 tbsp (15 ml) Dijon mustard (or yellow mustard)
  • 1 tbsp (10 g) capers, roughly chopped
  • 1 tbsp (4 g) flat-leaf parsley, roughly chopped
  • 1 tbsp (3 g) fresh dill, roughly chopped
  • 2 tsp (10 ml) lemon juice
  • 1 tsp (2 g) lemon zest, finely grated
  • ½ tsp (3 g) salt
  • ½ tsp (2 g) garlic powder
  • Black pepper, to taste
  • Cayenne pepper, to taste
  • 4–6 slices dark rye bread (or pumpernickel or sourdough)
  • 8–12 pcs cherry or grape tomatoes, sliced
  • 1 cup (113 g) shredded Monterey Jack cheese, white cheddar, or a mix of both
  • Garnishes (optional):
  • Fresh dill, chopped
  • Fresh parsley, chopped


  1. Preheat oven to 400°F (204°C) and line a baking sheet with parchment paper.

For the Tuna Salad

  1. In a bowl, combine the Greek yogurt, carrot, grated, red onion, mustard, capers, parsley, dill, lemon juice, lemon zest, salt, garlic powder, black pepper and Cayenne pepper. Mix thoroughly.
  2. Add the tuna and fold together. Cover and place in the fridge to allow flavours to meld while the bread is toasting.

For the Toasts

  1. Place 4–6 slices of dark rye onto the prepared baking sheet. Place into the preheated oven and toast for 8 minutes, flipping the slices over halfway through the toasting time.
  2. Remove toasts from the oven.
  3. Remove tuna salad mix from the fridge. Taste the tuna salad and season with salt and pepper, if necessary.

To Assemble

  1. Evenly divide and spread the tuna mixture onto the toasts. Top with tomato slices and an even amount of grated cheese.
  2. Place into preheated oven and bake for 5 minutes. Switch the oven to broil and broil for 2 minutes or until the cheese is melted and golden in a few areas.
  3. Remove from oven and sprinkle tuna melts with chopped dill and/or parsley. Serve immediately.

Chef's Tips

  • For a classic tuna melt, use mayonnaise instead of Greek yogurt.
  • Leftover cooked tuna can be used in place of the canned albacore tuna.
  • Canadian canned salmon can be substituted for tuna.
  • Minced dill pickles can be substituted for the capers.
