Sweet Potato Tuna Melts

Combining two of my favorite things into one to make this super satisfying and delicious meal. If you have been here for a while, you know that I love sweet potato toast. It’s so versatile and a great way to switch up from the regular “toast” (which I also love!). I personally love Japanese sweet potatoes but this would be so good on any regular sweet potato. Combine it with tuna salad to make the tastiest combination of Sweet Potato Tuna Melts.

Sweet Potato Toast Tuna Melts

Here’s what you need:

  • Sweet Potato (I used Japanese sweet potato here!)
  • 1 can of tuna
  • Mayo made with avocado oil (I used this one!)
  • Dijon mustard
  • Sea salt, pepper and garlic powder
  • Mozzarella cheese (or any cheese you’d like!)
