  1. Heat oven to 220C/200C fan/ gas 7. Lay the pastry out on a baking sheet. Pinch up the edges to form a border, pressing firmly into the corners. Prick the centre all over with a fork and pop in the oven for 10-15 mins.

  2. Meanwhile, mix the tuna and sweetcorn in a bowl and season.

  3. Remove the pastry from the oven, pressing the centre down with the back of a fork, as it will have puffed up a bit. Spread the crème fraîche across centre, spoon the tuna mix on top, then sprinkle over the cheese. Bake for 10-15 mins more, until golden, puffed up and cooked though. Sprinkle with chives and cut into quarters.

Made this tart which is mega easy, just added sliced red onion to the top of it. Had it warm for tea, had leftovers cold, it is 100% better cold the next day, absolutely delicious!!

I wasn't so enamoured with this meal. I found the tuna a bit dry after being in the oven and might try tuna in oil rather than in springwater next time. I also found the recipe a bit bland despite adding fried onions, peppers and mushrooms to tge tuna and sweetcorn. I think it would benefit from some kalamata olives or capers next time, as I don't add salt to my meals. Otherwise, a very easy and quick adaptable dish.

I agree with all the above comments. Quick, delicious, easy to prepare. However, mine was HUGE. Oh well. It suits itself to a picnic, or buffet where you can pre-cut it into smaller slices.

Simple, quick and tasty. The wonderful thing about this is that you can easily change the toppings, making it just how you want. I think next time I will add a more varied range of vegetables.

Great mid-week meal, quick and simple to make. Definitely would make it again and experiment with different toppings.

This worked so well as a quick weekday meal - so easy to prepare - will maybe add some more veg like peppers next time but added to our favourites.
