Slice the sirloin into paper thin strips. Peel & Slice the garlic cloves, then throw into a hot pan & oil. As soon as the garlic fried add the sirloin. Salt & pepper on the meat stirring a few times. Add some Chili peppers to taste, and a spoon of mustard, stirring some more, then pour into a bowl. The frying is about 1-2 minutes tops.

Place the pan back onto the stove, adding some oil. Chuck the finely chopped red onion & pickled gherkins into the pan frying a bit, then add the barbecue sauce frying little further and the sauce is ready literally.

Carry on toasting the half cut rolls both sides.

Assembling can be done by wrapping a little meat on the bottom of the bun, tossing it with a little juice, scooping on the topped barbecue sauce, putting some fresh baby sponge on top, and finally putting on the hat and serving.
