Baked Tuna Nicoise

Another day, another Weight Watchers meal to try. I’m actually really enjoying researching suitable recipes to eat on this diet that don’t compromise on flavour. I’d like to think that any of the recipes I try would be ones I’d be happy trying even if I wasn’t point counting. And my Pinterest boards can really testify to the amount of research I’ve done. A particular highlight being the revelation that making no sugar jelly and adding loads of fruit is a 0 point dessert! And I love jelly – I’m a child of the 80s after all.

So the latest recipe I wanted to try was Baked Tuna NicoiseI am a big fan of fresh tuna, and this recipe also included potatoes which I’ve been craving! Total Pro Points per person – 8. The recipe is really straight forward and all done using one pan, which saves on the washing up too. The flavours are obviously a classic combination and they still work really well together in a baked dish. I actually thought the red onions were the star of the show here – they went really soft and seemed to soak up all the lemon and caper flavours. Definitely a winner.
