Minced beef wellington - a jamie oliver favourite.

Preparation

• Peel and chop the onion, carrot, celery and potato into 1cm sized dice and finely chop the garlic.
• Clean and roughly chop the mushrooms so they're about 1 cm dice and place all vegetables into a frying pan with olive oil.
• Pick the rosemary leaves off the woody stalks, chop and add to the pan with the Worcestershire sauce.
• Fry and stir for about 8 mins or until the vegetables soften and colour.
• Add frozen peas and cook for another minute, then put vegetables into large bowl to cool completely.
• When cool, preheat oven to 180 deg C/Gas 4. Whisk the egg lightly in a cup.
• All combined and ready to go into pastry. Add the minced beef to the bowl with salt and pepper and half the egg. Scrunch together.
• Roll out pastry to size of small tea towel and place mince mix along one long side, in a sausage shape.
