A delicious, unusual combination of tuna, creamy yoghurt and cheese in shortcrust pastry. Lovely in summer or winter and great for using what you'd have in your cupboard anyway! My mother used to make this when you could only get Greek Yoghurt on holiday in Greece! She would describe it as mouthwatering - and it really is. Even friends who aren't too fond of canned tuna love this. It's definitely more delicious served cold but can be eaten from the oven.
Don't be tempted to top with sliced tomatoes - I've tried this and it tasted good but made the flan a little 'mushy' on top. The onion adds a crunch but only needs to be added if you like them. This is lovely served cold with salad and mayo or Creme fraiche
Instead of creamy Greek yoghurt you can use creme fraiche with a splash of lemon.
My husband who does not like tinned fish tried this for the first time on his birthday last month. I didn't tell him it was tuna and he loved it with a lamb's lettuce (Mâché in Brittany) and thinly sliced tomato salad. Am going to keep on NOT telling him what I'm giving him. Beetroot and Choccy cake next!! His reaction was worth even more than five stars. What a great day. - 20 Nov 2016
