Gluten-Free and Dairy Free! The ultimate paleo tuna melt! These deliciously healthy open-faced sandwiches have everything you love about a classic tuna melt without using any dairy or gluten. They're full of healthy fats and lean proteins, and even feature sweet potato toast instead of bread!
- Toast sweet potato slices two times on the highest toasting setting or until mostly cooked through.
- Meanwhile, combine tuna, avocado, tomatoes, onion, mustard, lemon juice, cumin, dried dill, salt, and pepper.
- Preheat broiler (at 500 degrees F). Lay sweet potato slices on a parchment paper-lined baking sheet. Top each slice with tuna mixture and non-dairy cheese. Place open-faced tuna sandwiches under broiler for 3-5 minutes or until cheese is melted and bubbly.
- Serve warm and enjoy!
