  • Total Time: 15 minutes
  • Yield: 4


  • 2 tablespoons mayonnaise
  • 1 teaspoon Dijon mustard
  • juice of half a large lemon (about 1½ tablespoons)
  • kosher salt
  • freshly ground black pepper
  • 1 6-ounce can American Tuna
  • ¼ cup finely diced red onion
  • ¼ cup chopped tarragon
  • 1 loaf of bread, bakery-style French or Italian
  • softened butter
  • 1 tomato, thinly sliced
  • 1 small bunch arugula
  • grated cheddar cheese


  1. Make the dressing: Whisk the mayonnaise with the mustard and lemon juice. Season with a pinch of salt and pepper to taste. Dressing will be thin. Taste, adjusting seasoning as necessary.
  2. Place tuna in a large mixing bowl. Add the onion and tarragon. Pour dressing over top and combine mixture gently with a fork. Set aside.
  3. Slice bread into eight rounds. Spread one side of each with the softened butter. Turn bread butter-side down. Begin assembling sandwiches: Place a small handful of arugula on four of the rounds. Top each with a mound of the tuna salad. Top tuna with tomato slices. Top tomato with cheese. Cover with bread.
  4. Heat a large nonstick skillet or griddle over medium heat. When hot, add a small dab of butter, then place sandwiches on the cooking surface. Cook until golden brown. Carefully flip each one, and cook on other side until golden brown.
  5. Remove from heat, cut in half, and serve.
