Preparing Your Runner Beans: You could use a mandolin or invest in a runner bean preparer, but I prefer to stick on some music and just prepare the beans with my knife and chopping board!
Caramelize the Onions: In this recipe, we saute the onions for just a couple of minutes until they’re soft. If you want an even more flavourful side dish, caramelise your onions (cooking and stirring frequently for 30 - 40 minutes) before adding the onion and runner beans. Note that this will of course extend the cooking time, but you could prepare your onions in advance!
