How to Make the Perfect: Cheese Toastie With Pink Onion and Chilli Relish

Inspired by a visit to New Covent Garden Market, noticing the huge quantities of perfectly edible fruit and vegetables wasted if not sold, Jenny Costa’s Rubies in the Rubble adheres to the belief that all good food should be cherished.

Food waste has become a hot topic, of late, with such increased social consciousness surrounding food consumption in 2017. A gourmet condiment brand with a prominent focus on sustainable food production, Rubies in the Rubble works directly with UK farmers to source fresh fruit and vegetables from surplus produce.

Following the colossal success of Dan Barber’s wastED on the roof of Selfridges, Rubies in the Rubble hosted an ‘Open Sandwich’ pop-up in Selfridges’ Food Hall last month, creating a menu of healthy lunch offerings with precious resources in mind. Every jar of Rubies products champions fresh produce and raises awareness about the need to value food. The ‘Pink Onion and Chilli’ relish, for instance, features eight salvaged Rosanna pink onions in each jar. These undersized or blemished pink onions can’t be machine peeled, though the energy used to grow these onions could power a light bulb for three hours.

“Made from British pink onions that are too stubby for supermarkets, our Pink Onion & Chilli relish is a sweet and sticky delight. Caramelised onions with a touch of heat makes this recipe the perfect companion to dishes from burgers to baked potatoes.”

“At Rubies in the Rubble we make our delicious condiments from fresh fruit and veg that would otherwise be discarded. Our ingredients have to pass a taste test, not a beauty contest. What matters to us is making the best relish around. So go on, have a dollop!”


Bread, 2 slices

Cheddar, to taste

Gruyère, to taste (optional)

Butter, a knob


Get a slice of your favourite bread (if in doubt, you can’t beat a good sourdough) and butter both sides.

Add a layer of Rubies in the Rubble pink onion and chilli relish. Grate some cheddar on top (if you’re feeling fancy, use half cheddar, half gruyère).

Then add the top slice of bread (again, with both sides buttered), and whack in a hot frying pan until the cheese is melted and the bread is golden. Flip to toast on the other side.

Rubies in the Rubble condiments can be purchased from Waitrose, Ocado, Fortnum & Mason, Selfridges, Lakeland, Cook, QVC, and from Rubies in the Rubble at Borough Market. Further information can be found at
