Expert Tips

  1. You can use any type of keto bread you like for this Keto Tuna Melt, however I recommend a 90 Second Keto Bread because it's fast to make!
  2. Other bread options would be sliced keto bread, Low Carb Onion Bun sliced in half or a Keto Hot Dog Bun sliced in half.
  3. This recipe can be doubled, tripled, quadrupled, or multiplied however you like depending on how many tuna melts you may need!
  4. When broiling the cheese, make sure to keep a close eye on your Keto Tuna Melt because the cheese will burn very quickly!
