Fresh, easy and delicious!

Beef rocket sandwich with horseradish and balsamic sauce, yum!

Fry gently some shallots (finely sliced) in an olive oil for about 10 minutes then add 2 tbs of balsamic vinegar
Grilled the steak for 2-3 minutes

Spread the horseradish sauce on a walnut bread (toasted). Add the fried shallots and rare beef with some rocket salads on the top.

AMAZING!
