Roast, the upmarket restaurant in Borough Market's Floral Hall, has opened its own sandwich stall in the market using produce sourced from neighbouring traders.
Roast To Go's bread comes from the Flour Power City bakery in Stoney Street who have made caraway seed bread and bridge rolls for the new venture.
The stall opens at 7am Monday-Saturday offering bacon rolls (£3.25) made with maple cured streaking bacon supplied by market stalwart Peter Gott of Sillfield Farm.
Sillfield's sausage supremo Eric Reeve has devised a special Lincolnshire sausage made with rare breed pork and fresh sage from Booths.
At lunchtime the menu changes to include pastrami, salt beef and smoked trout sandwiches.
The pastrami is produced by Farmer Sharp from peppered briskets of his Galloway cattle.
Tea, coffee and orange juice are competitively priced at just 95p.
Parent restaurant Roast was opened in October 2005 by Iqbal Wahhab, founder of The Cinnamon Club.
Roast To Go is open Monday-Saturday 7am-3pm.
