Ingredients
- 2 large English cucumbers, washed and dried
- 1 can (5 oz) tuna packed in water, drained and flaked
- 3 tbsp mayonnaise (use avocado oil-based mayo for extra healthy fats)
- 1 tbsp Dijon mustard
- 2 tbsp finely chopped red onion

Instructions
- Prepare the Cucumbers: Slice each cucumber in half lengthwise. Using a spoon, gently scoop out the seeds and some flesh to create a hollow “boat” about 1/2 inch thick, while keeping the cucumber skin intact for sturdy cups.
- Drain and Flake Tuna: Open the can of tuna,drain thoroughly,and use a fork to break it into flaky pieces. This ensures even mixing and bite-sized chunks in the salad.
- Mix the Tuna Salad: In a medium bowl, combine the flaked tuna, mayonnaise, Dijon mustard, red onion, celery, fresh dill, and lemon juice. Stir gently to avoid mashing the tuna, seasoning with salt and pepper to your preference.
- Optional Egg Addition: If desired,fold in the chopped hard-boiled egg for extra texture and richness.
- Fill the Cucumber Boats: Spoon the tuna salad mixture generously into each cucumber half,mounding slightly for an appealing presentation.
- Chill and Serve: For maximum freshness, cover the filled cucumber boats with plastic wrap and place in the refrigerator for 10 minutes before serving. This crisp chill enhances the flavors.
Chef’s Notes & Tips for Success
- Choose Firm, Fresh Cucumbers: Firm cucumbers yield the best “boats” that don’t wilt under the weight of the filling.
- Mayonnaise Alternatives: Try mixing in avocado or Greek yogurt for a lighter, tangier salad but adjust salt accordingly.
- Flavor Boosters: Add a pinch of smoked paprika or a dash of hot sauce for a subtle kick.
- Make Ahead: Prepare the tuna salad up to a day in advance; keep the cucumber boats separate to maintain optimal crunch.
- substitution Ideas: Swap tuna with canned salmon or cooked shrimp for different keto-friendly options.
