Keto Tuna Taco

Keto Tuna Taco

How about trying a flavorful Tuna Swiss Melt with a twist? Start by mixing your favorite canned tuna with creamy mayo, tangy mustard, zesty dill relish, a pinch of salt, pepper, and a dash of seasoning salt for an extra kick.

Once your tuna salad is ready, spoon it onto a slice of Swiss cheese, allowing the cheese to cradle the tuna mixture. Then, sprinkle some everything bagel seasoning on top for a burst of savory flavor and a delightful crunch.

Place another slice of Swiss cheese on top to create a cheesy tuna sandwich masterpiece. Finally, grill or bake until the cheese is melted and gooey, and the tuna filling is warmed through.

The result? A mouthwatering Tuna Swiss Melt that’s bursting with savory goodness and sure to satisfy your cravings. Enjoy it as a quick and easy lunch or serve it alongside a crisp salad for a deliciously satisfying meal.
