Ingredients

  • 10 ounces canned tuna packed in oil, drained
  • 1/2 cup store-bought tzatziki
  • 1/4 medium red onion, diced
  • 1/2 teaspoon fresh lemon juice
  • 8 slices whole-grain bread
  • 4 slices Gruyère cheese or other melting cheese
  • 4 leaves green-leaf lettuce or romaine, or 1/2 cup packed arugula leaves or any lettuce or leafy greens
  • 1 teaspoon extra-virgin olive oil
  • 2 tablespoons chopped mixed fresh herbs (dill, parsley, mint)
  • Kosher salt
  • Freshly ground black pepper
  • 1 avocado, pitted and cut into 1/4-inch (6-mm) thick slices

Instructions

  • Dump the tuna and cucumber yogurt dip or tzatziki in a bowl and use a fork to combine them until the tuna is nicely coated yet still chunky. Add the onion and 1/4 teaspoon lemon juice and gently fold everything together.
  • Preheat the broiler on your oven or preheat your toaster oven. Lightly toast the bread under the broiler or in your toaster oven. Remove 4 slices of toast and set aside. Place 1 slice cheese on each of the 4 remaining slices of toast and return them to the broiler or toaster oven until the cheese melts, 1 to 3 minutes. Watch them carefully and don’t turn your back!
  • In a medium bowl, whisk together the olive oil and 1/4 teaspoon lemon juice. Add the greens and herbs and toss gently to coat. Sprinkle with salt and pepper and toss again. Divide the greens among the 4 plain slices of toast. Scoop an equal amount of tuna over the greens, arrange the avocado slices on top, and sandwich with the toasted cheese slices, cheese side down. Cut the sandwiches on the diagonal and serve immediately.
