Before I start let me just say this: don't be put off by the recipe containing trout! I know a lot of people are funny about fish, and often stick to what they know. Trout is a lovely flavour; quite similar to salmon (a little less 'fishy' in my opinion!), and in this recipe you could substitute the trout for salmon if you wish. This is a recipe from one of Fay Ripley's books which I just love - so may simple recipes with everyday ingredients.
You will need: (for two people)
375g pack puff pastry (you'll only use half)
2 trout fillets
2 tablespoons pesto
100g pack spinach
Start off by cutting the pack of pre-rolled pastry in half. You can make your own pastry of course, but... well, why would you? Life is too short. Lay this on a baking tray lined with some grease proof paper. Wilt your spinach by shoving it all in a pan with the lid on over a gentle heat for a few minutes, then press as much water out of the spinach as you can on some kitchen towel. Lay the spinach in the middle of the puff pastry, and then top with the trout. Spread over a couple of tablespoons of pesto and finish with a sprinkling of lemon zest. Bring the pastry together into a parcel shape and squeeze the edges to seal. Brush over a little milk and then pop in the oven (180c) for about 25-30 minutes.
Chop in half across the two fillets (rather than down between the two) and serve with steamed summer green veg and new potatoes; we're obsessed with runner beans at the moment! My parents, and our neighbour have both had a huge harvest so we keep getting given big bags of the stuff... delish!
