Ingredients
- 1 can (5 oz) Canned tuna (packed in water or oil)
- 2 tablespoons Mayonnaise
- 1 teaspoon Dijon mustard
- 0.25 teaspoon Salt
- 0.25 teaspoon Black pepper
- 1 large (sliced into rounds) Cucumber
- 0.5 medium (optional, sliced) Avocado

Instructions
Drain the canned tuna thoroughly and transfer it to a mixing bowl.
Add mayonnaise, Dijon mustard, salt, and black pepper to the bowl. Mix well until the tuna mixture is creamy and well-combined.
Wash and slice the cucumber into thin, even rounds. Additionally, slice the avocado if you're using it.
Lay two large lettuce leaves on a clean work surface. These will act as the base for the sandwich.
Spread an even layer of the tuna mixture onto the lettuce leaves.
Top the tuna layer with cucumber slices and avocado slices (if using).
Cover with another lettuce leaf to create a sandwich, or roll it for a wrap-style presentation.
Repeat the process for the second sandwich or store remaining filling in an airtight container in the fridge for up to 2 days.
Serve immediately and enjoy your low carb tuna mayo sandwich!
