  • 2 small zucchini
  • 2 tbsp olive oil divided
  • 1 tin of tuna drained
  • 1 celery stalk minced
  • ¼ medium red onion minced
  • 2 tablespoons fresh lemon juice about half a lemon
  • ¼ tsp dried dill
  • ½ cup cheese I used ¼ cup parmesan and ¼ cup feta


  1. Preheat your oven to 400 and line a baking sheet with parchment
  2. Slice the zucchini in half and using a teaspoon, scoop out the centre, about an inch. Brush the four zucchini halves with 1 tablespoon of olive oil and roast for 15-25 minutes. This will depend on the size of your zucchini. You want them to be tender, but not mushy. I used a fork to see how easily I could pierce the side and did a little touch test. Look for them to begin browning slightly on the sides

  3. Meanwhile, mix together the tuna, celery, onion, and dill with the other tablespoon of olive oil and the lemon juice
  4. Grate the parmesan cheese
  5. Once the zucchini is done, take it out of the oven and turn on the broiler. Fill your canoes with the tuna mixture and top with the cheese
  6. Broil for 2-3 minutes or until the cheese has browned and is crispy on top
