Roast Beef Wrapped in Prosiutto

• 1kg beef fillet
• sea salt
• pepper
• 2 Tbsp olive oil
• 9-12 long slices prosciutto
• 1 Tbsp dijon mustard

Season beef and rub over olive oil. Sear beef on all sides. Allow to cool a little.  Arrange the prosciutto slices, overlapping slightly to make a large rectangle, on a piece of non-sick paper and spread with mustard. Put the beef on top and bring the prosciutto up over the sides and enclose the beef. Tie with kitchen string.

Roast at 190 degrees. 10 minutes per 500g plus 10 minutes for med-rare.
