You’ll Need:

  1. Preheat oven to 325 F. Spread out the mozzarella slices onto 2 parchment paper (Not Wax Paper) lined baking sheets. Then in a bowl mix the drained cans of tuna with the mayonnaise and minced celery. Stir until very well combined.
  2. Bake the cheese slices, until fully melted, approx. 4-5 mins. Remove from the oven and let cool slightly before adding a few spoonfuls of tuna to the corner of each of the cheese shells. Then fold the squares in half into triangle shapes. Firmly press the sides closed.
  3. Return to the oven for another 5 - 10 minutes or until the edges are golden brown.
