Using a food processor, pulse toasted bread into bread crumbs. (You can use any Martin’s product such as Old-Fashioned Real Butter Bread or 100% Whole Wheat Potato Bread or Rolls.)
In a medium bowl, mix together egg, breadcrumbs, celery, mayonnaise, onion, and chili sauce. Add tuna and fold to combine. Shape into four equal sized patties.
In a large skillet, heat butter over medium heat. Cook patties until lightly browned, 4-5 minutes per side. Serve on Martin’s 100% Whole Wheat Potato Rolls, topped with lettuce and tomato if desired.
