How to store and freeze

Tips for best results
- Use a serrated knife to slice the cucumber for even rounds.
- If you’re cooking for guests, consider preparing a larger batch of tuna mixture to make additional bites.
- Customize the toppings by adding other ingredients like diced bell peppers or olives for extra flavor.
- Store the cucumber slices separately if you anticipate leftovers to maintain their crunch.
Ways to change it up
Feel free to experiment with the flavor profile of the tuna mixture. You can add diced celery for crunch, or swap mayonnaise for Greek yogurt for a lighter option. If you want more heat, increase the sriracha or add a dash of cayenne pepper. For a Mediterranean twist, mix in some feta cheese or olives.
