Mozzarella Filled Steak Rolls

Directions

1. 1
   Heat oven to 450°F
2. 2
   Season steaks, place a few basil leaves on each and split the mozzarella between them.
3. 3
   Bring the sides of the steaks together to make an open parcel, securing the edges with a toothpick. If making up to a day ahead, cover and chill.
4. 4
   Heat a heavy-based roasting tin on a high heat, add the oil and brown the beef on all sides - this should take about 1 min in total and the meat will still be rare in the middle.
5. 5
   Add the peppers, their oil and the olives to the tin, pour over the vinegar, then roast for 2-3 mins for medium rare, longer for well done.
6. 6
   Cover with foil and leave to rest for up to 5 minutes Scatter over remaining basil before serving.
