Monstrous Mini Beef Wellingtons

7oz frozen puff pastry
21/2oz Boursin cheese
1/2lb trimmed beef fillet, cut into cubes
salt and freshly ground black pepper
l large onion, beaten lightly

Preheat the oven to 200C/400F.

Roll out the puff pastry until it is just under 1 inch in thickness and cut the pastry into 1 1/2 -inch squares.

Spoon a 1/4 tsp of the cheese in the centre of each pastry square. Season the beef with salt and pepper and set a cube on each pastry square. Fold the pastry over the beef, neatly tucking in the corners.

Lightly brush each pastry with the beaten egg. Bake for about 12 minutes, or until puffed and golden brown.
