Ingredients needed to make this tuna salad:

  • canned wild-caught tuna: alwayssss opt for wild-caught fish!
  • mayonnaise: (I always use the Primal Kitchen mayo, as I find it’s made with the cleanest ingredients).
  • dijon mustard: because what’s tuna salad without some dijon mustard mixed in for flavor?!
  • celery: for the best crunch (and a great way to sneak veggies in)!
  • red onion: also for the crunch-factor and gives the tuna salad lots of flavor.
  • lemon juice: love the flavor that it gives this tuna salad.
  • garlic: for flavor!!
  • salt and pepper: adjust to your liking!
  • bread: I recommend whole wheat, sourdough, gluten-free or paleo bread.
  • cheese: always opt for grass-fed and organic. I like swiss or cheddar for this. I buy a block of cheese so I can freshly grate it on top. Sliced cheese works as well.
