Heat oil in a large saucepan over a medium heat
Add onions and cook for around 5 minutes - until translucent, add a splash of water if it starts to stick
Add in carrots, potato and beans and add enough boiling water to cover everything
Crumble in stock cube or add bullion and stir well
Simmer gently for around 20 minutes, check to see if the potato is done and carrots are cooked but with some bite. If not, continue to simmer and check again in 5 mins until done
Once done, add in kale or greens and cover the pan with a lid. Let the greens wilt for around 2-3 minutes.
Take out half of the soup and carefully (it's hot!) blend in a blender or with a stick blender.
Add blended soup back to pan with the rest of the soup, stir and heat through.
Taste and season to your liking with salt and pepper
Serve up with hunks of your fave bread
