1Sear the roast beef in a frying pan with oil until browned on all sides.
2Wrap the seared beef in aluminum foil and let it rest for 15 minutes.
3While the beef is resting, prepare the bread cone by flattening a slice of bread with a rolling pin, rolling it into a cone shape, and securing it with a toothpick.
4Deep-fry the bread cone until golden brown.
5Once the resting time is over, slice the beef thinly.
