Served in crisp, cool cucumber boats, this recipe is the perfect light lunch, elegant appetizer, or post-workout snack. It’s a simple, clean, and incredibly satisfying way to enjoy tuna, paired with a quick and creamy chocolate drink for a truly unique meal.

Ingredients

• 70 g / 2.5 oz cucumber, raw, peeled
• 30 g / 1 oz canned light tuna in water, well-drained
• 26 g / 2 tbsp olive oil
• 35 g / 2.5 tbsp heavy cream (40%)
• 5 g / 1 tsp sugar-free chocolate syrup
• Salt and freshly ground black pepper, to taste

Instructions

1. Prepare the Cucumber Boats: Peel the cucumber and slice it in half lengthwise. Use a small spoon or a melon baller to scoop out the seeds, creating a hollow “boat.”2. Create the Tuna Filling: In a small bowl, combine the thoroughly drained tuna and the olive oil. Mix vigorously with a fork until the oil is fully incorporated and the mixture is smooth and creamy.3. Assemble and Season: Carefully spoon the creamy tuna mixture into the hollowed-out cucumber boats. Season generously with salt and freshly ground black pepper to your liking.4. Mix the Chocolate Cream Drink: In a separate glass, stir the heavy cream and chocolate syrup together until combined. Add a splash of water and mix to reach your desired “milk” consistency.

Nutritional Information

• Nutritional ProfileThis recipe is a fantastic low-carb and keto-friendly option. It’s rich in omega-3s from the tuna and packed with monounsaturated fats from the olive oil, making it a heart-healthy choice. The use of cucumber instead of bread or crackers keeps it light, hydrating, and gluten-free.

Pro Tips

• A melon baller is the perfect tool for neatly hollowing out the cucumbers without piercing the skin.
• For the creamiest filling, ensure your canned tuna is drained completely dry before mixing in the olive oil. Any excess water will prevent it from emulsifying properly.
• Opt for small, firm baby cucumbers or Persian cucumbers for a better texture and a more elegant, bite-sized presentation.
• Elevate the flavor by adding a squeeze of fresh lemon juice, some finely chopped dill, or a pinch of red pepper flakes to the tuna mixture.

FAQ

Q: Can I make these tuna cucumber boats ahead of time
A: For the best texture, it’s recommended to prepare the tuna filling in advance and store it in an airtight container in the fridge. Hollow out and fill the cucumber boats just before serving to ensure they stay crisp and don’t become watery.

Q: What other flavors can I add to this tuna salad
A: You can easily customize this recipe. Try adding a squeeze of fresh lemon juice for brightness, some finely chopped dill for a fresh herby flavor, or a pinch of red pepper flakes if you enjoy a little bit of heat.

Q: Is there a good substitute for the cucumber boats
A: Yes, if you don’t have cucumbers, this olive oil tuna salad is also delicious served in hollowed-out bell peppers, on crisp lettuce wraps, or with your favorite low-carb crackers.
