How to Make Tuna Cucumber Boats
Step 1 – Mash the tuna

Step 2 – Mix the filling
Add celery, onion, Greek yogurt, French mustard, salt, black pepper, and dill. Mix until everything is well combined.
Step 3 – Prepare the cucumbers
Slice the cucumbers lengthwise down the middle. Use a spoon to scoop out some of the inside to make room for the filling.
Step 4 – Fill the cucumber boats
Spoon the tuna mixture into the cucumber halves, spreading it evenly.

Variations / Substitutions
Use canned salmon or shredded chicken instead of tuna for a different protein.
Swap Greek yogurt with avocado or a light mayonnaise if preferred.
Add lemon juice for extra brightness or a pinch of paprika for mild warmth.
Use gluten-free mustard if you need the recipe to stay gluten-free.
Storage & Leftovers
Store leftover tuna filling in an airtight container in the refrigerator for up to 3 days.
For best texture, store the cucumber halves and tuna mixture separately until ready to serve.
Filled cucumber boats are best enjoyed the same day because cucumbers release moisture over time.
