Recipe by @fufuinthekitchen
This tuna salad recipe includes many of the classic ingredients: celery, red onion, fresh dill, mayonnaise and lemon juice. The flavors get elevated with the addition of tangy, slightly sweet banana peppers, spicy brown mustard and chili flakes. Layered on toasted bread with Swiss cheese, tomato and fresh avocado, this sandwich is reminiscent of a childhood favorite with grown-up flavors.
