Gather your ingredients for a simple tuna salad sandwich

To make this simple tuna salad sandwich, you can start by gathering your ingredients. For this recipe, you will need tuna, Dijon mustard, mayonnaise, diced celery, diced red onion, salt, lemon pepper, and rye bread.

Mix the tuna, Dijon, and mayo

Add the tuna into a small bowl, flaking it with a fork. Then, add the Dijon mustard and mayonnaise. We recommend using a chunk light tuna — the kind found in the aluminum pouch or the can. But feel free to use any other type of cooked tuna you would like, such as wild caught, albacore, or yellowfin.

Add the remaining salad ingredients and stir well

Then, add the diced celery and red onion into the bowl. If you like a chunky-textured tuna salad, like us, keep the veggies in a standard dice size. If you want a more uniform consistency, you can dice your celery and onion even more finely. 

Finally, add the salt and lemon pepper before stirring the tuna salad well. We feel that lemon pepper is one of the most underused seasonings out there — it adds a little brightness and zest to this tuna salad recipe.

Toast the bread and make your sandwich

Lastly, toast up the rye bread slices. We are big fans of seeded rye bread for use with our tuna salad sandwiches, but feel free to substitute other types of bread, such as sourdough or whole wheat. Once the bread is toasted, scoop the prepared tuna salad onto the slices, assemble into a sandwich, and enjoy.
