1 Salmon Fillet per person (I prefer smoked but whatever your preference)
Block Feta Cheese, chopped
2-3 tbs Pesto
2-3 tbs Pine Nuts
Puff Pasty (ct. strictly store-bought!)
Chop the spinach into small strips and fry until paste-like. Use a fine sieve to get rid of any excess water (ct. use frozen spinach - I would say it actually works better, although you must sieve it or else it'll be too soggy). Add feta and pesto and cook until cheese has melted and combined. Toast pine nuts.
Roll pastry out to fit fillet, plus app. 1 inch either side.
Spread spinach mixture on pastry. (tip - it's actually better if you've done the spinach mixture in advance and let cool before spreading to stop the pastry getting soggy).
Sprinkle pine nuts (miss step if small children are eating).
Add salmon and fold over, as below:
Cut slits on top, brush with egg/milk and put in oven for 25-30 minutes, 200C.
