Mediterreanen Spinach And Beef Pastry Roll - cooking recipe

Ingredients

1/4 cup butter
2 None onions, peeled and finely chopped
2/3 lb young spinach
1/2 cup couscous
2 None garlic cloves, chopped
1/2 lb carrots, peeled and grated
2/3 lb ground beef
1 medium egg, separated
1/2 tsp chili flakes
17.3 oz package puff pastry (use half)
1 1/4 cups Greek yogurt
1 oz mint, leaves picked and chopped

Preparation

Heat half of the butter in a large lidded frying pan, add half the onion and cook for 2-3 mins. Add the spinach, cover and cook over a gentle heat for 2 mins. Transfer to a large sieve, press with the back of a spoon to remove any excess water.
Place the couscous in a saucepan with 1/2 cup of just-boiled, salted water. Cover with a lid and set aside for 5 mins, allowing the couscous to expand and soak up all the water. Fluff with a fork.
Meanwhile, heat the remaining butter, add the remaining onion and the garlic. Cook over a gentle heat for 5 mins. Add the carrots and cook for 3 more mins. Set aside to cool for 15 mins.
Preheat the oven to 425\u00b0F. Place the carrot mix in a large bowl with the couscous, beef, egg white and chili flakes. Season with salt and freshly ground black pepper and knead to combine.
Unroll half the package of puff pastry (about 9 oz) on a work surface, cover with the spinach, then spoon the beef and couscous mixture along the long side. Roll-up. Brush the underside of the seam with water to seal. Transfer to a baking sheet lined with baking parchment seam-side-down.
Lightly score the top in a diagonal pattern with a sharp knife. Brush with the egg yolk (whisk in a little water to loosen, if necessary). Bake for 30 mins. Check after 20 mins and cover with foil if necessary.
Mix the yogurt with most of the mint, spoon into a serving dish and sprinkle with the remaining yogurt. Serve with the beef roll.
