This is a fancy tuna salad sandwich! If fresh tuna steaks aren’t an option, canned tuna will always work – but the tuna steaks certainly add an upscale element to this recipe. The habanero mayonnaise is both spicy and cooling. A great, easy recipe for a hot summer weeknight!

Grilled Tuna Salad Sandwiches with Habanero Mayonnaise

by Healthy Way To Cook


  • 3 cups fresh lemon juice
  • 1/2 to 1 whole habanero chile, chopped
  • 1 teaspoon grated lemon zest
  • 1 cup organic mayonnaise
  • Salt and freshly ground pepper
  • 1 small red onion, finely diced
  • 1 large stalk celery, finely diced
  • 2 tablespoons chopped fresh flat-leaf parsley
  • 4 (8 ounce) tuna steaks
  • Olive oil
  • 8 slices hearty bread (Italian, French, ciabatta, or country white)
  • Watercress


In a small saucepan, pour the 3 cups of lemon juice, and put over medium high heat; bring it to a boil and cook until liquid is reduced to 1/2 cup; remove and let cool slightly.

In your blender, pour the reduced lemon juice, habanero chili, lemon zest, and mayonnaise and blend until smooth; season with salt and pepper, taste and adjust as desired; then pour mixture into large bowl and add the onions, celery, and parsley; set aside.

Heat grill to high.

Drizzle olive oil over tuna, coating lightly, then season with salt and pepper, flip and repeat.

When grill is hot, put tuna on grill and cook 3 minutes, flip and cook 3 more minutes, making sure you have good charred marks on both sides; you want the tuna to be done medium.

Remove from grill and let rest for 5 minutes before flaking or chopping.

Add the flaked tuna to the lemon/mayonnaise mixture and gently toss together until tuna is coated well.

Make sandwiches by dividing the tuna evenly between 4 slices of bread, then topping each with watercress, then covering each with remaining 4 slices.
