This is one of my favorite recipes! I love the sweetness of the sweet potato, the zesty taste of the lime, the salty flavor from the tuna, the fresh taste from the yoghurt, the chili makes it hot and the onion gives it a depth of flavor! Great recipe!

This is absolutely yummy. I didnt have high epectations the first time I made it but the flavours are amazing together. Healthy, delicious and sooo easy. What more do you need?!

Absolutely loved it

I loved this, thought it was delicious. I mixed the tuna, chilli and chopped up the onion and then topped it with everything else and added some feta cheese too. Will only ever do sweet potato jackets again, so much tastier! I did 2 in the oven for 45 mins as i always prefer the taste & texture this way to microwaving.

Delicious! Super filling and really low fat so great when on a diet. All the ingredients work so well together.

Surprisingly good! I added chilli oil instead of peppers and it turned out REALLY good! This is very unusual combination, but it's quick, healthy and delicious - I will definitely cook it more often from now on!

Great! Good for a fresh-tasting, easy, light lunch.

Loved this recipe. Would cook the potatoes for less time next time though. Great low fat supper!

18-20 mins is a bit over-kill! They'll do in much less in a microwave, even a low wattage one! Happily, sweet potatoes cook more speedily than regular potatoes -- what's not to like!? They're almost always the better option! And GREAT with something a little salty-sour like tuna!

I thought this might be a bit dry so I mixed the ingredients up with a table spoon of the yogurt then served with extra yogurt onion slices and lime juice. It was fabulous, tangy, sour, fishy, creamy balancing beautifully with the sweet potato....yummy

umm . not sure i got this right. Sweet potatoes had odd texture, coriander was not as strong tasting as I've had before n chilli ghad no kick!
I may try again, but instead i'll steam sweet pototoes, test coriander before i buy n get stronger chilli.
I like the combo of tuna lime n yogurt though.

I absolutely love this recipe. It's so simple and as a student is a great alternative to the normal jacket potato. I didn't have yogurt so improvised with salsa, mayonnaise and sour cream and onion dip, having a section of each. I must say that both the salsa and sour cream dip add that extra dimension that you don't get from yoghurt. Definitely worth trying!

Have made this a few times now. It's cheap and easy and I love sweet potato. The lime makes a lot of difference and the greek yoghurt is a must!

Anyone watch Hugh Fernely Whittingstalls Fish fight on Channel 4 last week or seen the Greenpeace tinned tuna league table?


Make sure you use pole and line caught tuna for this dish rather than that has been caught using large nets which kill dolphins, turtles and sharks as by-catch. pole and line tuna can be found at Sainsbury's, marks & spencer and waitrose but unsure about the others...

Was very sceptical to this one, but was pleasantly surprised. The flavors go well together and it's such a healthy mix of veggies and meat. Will make again as soon as possible!

can you freeze this and would a little bit of feta cheese go nice and what other filling besides tuna

This was so easy, and was fantastic! Healthy, cheap, easy, and very delicious. Five stars.

Unusual but really tasty and easy to do. Definitely make again. I cooked the red onion though and also added some cherry tomatoes!
