Rubies in the Rubble has been fighting food waste with relish since 2011 and now the condiment brand has set up shop in Selfridges with an ‘Open Sandwich’ pop-up. The brand is all about sustainable food production and make condiments out of fresh fruit and veg that would otherwise go to waste – think wonky cucumbers and overripe tomatoes. You can get your hands on four open sandwiches, including Pulled Beef & Pickle with Chipotle Ketchup, Spring Veg & Blue Cheese with Piccalilli, Avo & Beet Hummus with Pink Onion Relish and Nut Butter & Banana with Banana & Chilli Ketchup. And you can forget the bread because each option will instead be served up on toasted crackers made from the juice pulp from Daily Dose’s Cold Pressed range; you can expect everything from a Carrot & Tumeric cracker to Beetroot and Ginger.
