Tins / Cans / Packets

Organic tinned and packet food from Biona, Mr Organic, Clearspring, Fish4Ever and Organic Kitchen.

Beans, chickpeas, lentils and pulses; chopped and plum tomatoes, passata and purée; sweetcorn, artichokes, ratatouille and pickled vegetables; coconut milk; tinned fish; soups and ready meals.

Tinned pulses are already cooked — they need warming, not boiling. Rinsing them under the tap removes most of the added salt and the starchy liquid, though that liquid from a chickpea tin (aquafaba) whips like egg white and is worth keeping if you bake vegan.

Tinned food keeps for years unopened and loses very little nutritionally against fresh, since it's sealed and heated once rather than sitting in transit.
