Ingredients

2 large cucumbers
1 6-ounce can of albacore tuna
2 Tbsp. plus 1 tsp. mayonnaise
½ tsp. Dijon mustard
¼ tsp. white wine vinegar
1 Tbsp. Kalamata olives
1 Tbsp. finely diced red onion, optional
1 celery stalk
1 Tbsp. dill, finely chopped
Freshly ground pepper to taste

Directions

Slice the cucumbers in half horizontally. Hollow out the seeds and slice a teeny bit of the base so that each half can stand on its own.

Stir together the mayonnaise, mustard and vinegar in a medium bowl. Drain the tuna and add it to the dressing, flaking it with a fork. Fold in the olives, celery and onions. Taste for seasoning. Scoop a quarter of the tuna salad into the hollow of each cucumber half.
