Open-Faced Buckwheat Crêpes with Tuna, Arugula and Dijon Vinaigrette

For the most delicious results, use the best olive oil–packed tuna you can find.


  • 3/4 cup buckwheat flour
  • 2 large eggs, beaten
  • 1 1/3 cups milk
  • 8 ounces bonito tuna in olive oil, drained
  • 1 small green apple, cored and cut into 1/4-inch dice
  • 1 small shallot, minced
  • 1/3 cup mayonnaise
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon Dijon mustard
  • 1 tablespoon red wine vinegar
  • Sea salt
  • 1/4 cup olive oil, plus more for brushing
  • 5 ounces arugula


  1. In a medium bowl, whisk the buckwheat flour with the eggs and half of the milk until lump-free. Add the remaining milk and whisk until smooth. Refrigerate the batter for 20 minutes.
  2. Meanwhile, in another medium bowl, mix the tuna with the apple, shallot, mayonnaise and lemon juice.
  3. In a small bowl, whisk the mustard with the vinegar and salt. Gradually whisk in the 1/4 cup of olive oil, then season the vinaigrette with salt.
  4. Line a plate with wax paper. Heat an 8-inch nonstick skillet and lightly brush with olive oil. Add 1/4 cup of the batter to the skillet and swirl to coat the pan. Cook over moderate heat until the edges begin to pull away from the pan, 30 seconds to 1 minute. Flip the crêpe and cook 30 seconds to 1 minute longer. Transfer the crêpe to the prepared plate and repeat with the remaining batter.
  5. Divide the tuna salad between the crêpes and top with the arugula. Drizzle with the vinaigrette and serve.
