Health benefits of sweet potato
- Nutrient-Rich: Sweet potatoes are packed with vitamins, minerals, and fiber, making them a nutritious choice for any meal. They provide a good source of vitamin A, vitamin C, potassium, and antioxidants, which support overall health and immune function.
- Heart Health: Sweet potatoes are low in sodium and high in potassium, which helps regulate blood pressure and reduce the risk of cardiovascular disease. Their fiber content also supports heart health by lowering cholesterol levels and improving digestion.
- Weight Management: Sweet potatoes are low in calories and high in fiber, helping you feel full and satisfied for longer periods. Their natural sweetness can also satisfy cravings for sugary foods, making them a healthy alternative for weight management and controlling appetite.
Health benefits of tuna
- Lean Protein Source: Tuna is a lean protein source that provides essential amino acids necessary for muscle repair, growth, and overall health. It is low in saturated fat and calories, making it an ideal choice for those looking to increase protein intake without consuming excess calories.
- Omega-3 Fatty Acids: Tuna is rich in omega-3 fatty acids, particularly EPA and DHA, which have numerous health benefits. These fatty acids support heart health by reducing inflammation, improving blood vessel function, and lowering triglyceride levels, reducing the risk of cardiovascular disease.
- Nutrient Density: Tuna is packed with essential nutrients such as vitamin D, selenium, and B vitamins, which are important for bone health, immune function, and energy metabolism. It is also a good source of iron, magnesium, and potassium, further enhancing its nutritional value and health benefits.
This Tuna Salad Sweet Potato Boat was inspired by my Shredded Tofu and Avocado Bagel. If you're wanting a vegetarian high protein version of this, use this recipe as some Inso and use tofu instead of Tuna!

Instructions for Tuna Salad Sweet Potato Boat

Roast the sweet potatoes

Mix together the tuna, mayo, avocado, dill, onion, chilli and salt

Add the lettuce and tuna mix to the sweet potato

Top with the grilled corn and parmesan and enjoy!
Want to save time? If you want to save 5 minutes and a dish or two, use canned corn instead. Although grilling the corn will provide another element of flavour, adding as is from the can is just as good!
Substitutions
- Vegan Option: Replace tuna with chickpeas or white beans for a plant-based alternative. Substitute mayo with vegan mayo or hummus.
- Dairy-Free Alternative: Omit Parmesan cheese or use a dairy-free cheese alternative.
- Potatoes: Use any type of potato. Purple sweet potatoes are great and white potatoes are perfect too!
Variations
- Mediterranean Twist: Swap tuna for grilled chicken and add sun-dried tomatoes, olives, and feta cheese to the salad for a Mediterranean-inspired flavour.
- Asian Fusion Variation: Replace tuna with cooked prawns or tofu. Mix in soy sauce, sesame oil, and sesame seeds to the salad, and serve with a side of steamed bok choy.
Storage
Store the potatoes separately from the tuna mix. The tuna mix will last 24 - 48 hours in the fridge, add an extra squeeze of lemon though to help the avocado stay green. The sweet potato will last 3 - 4 days in the fridge. When reheating I would just microwave the sweet potato and eat the tuna mixture cold because warm avocado is not pleasant (in my personal opinion haha)
Top tip
For extra flavor, try seasoning the sweet potatoes with a sprinkle of smoked paprika or garlic powder before roasting. This simple addition will enhance the taste of the dish and add a delicious smoky aroma to the sweet potatoes. Enjoy your Tuna Stuffed Sweet Potatoes for a nutritious and satisfying meal!
